cmd/syncthing: Start CPU usage monitoring not from init (fixes #4183)

Starting stuff from init() is an antipattern, and the innerProcess
variable isn't 100% reliable. We should sort out the other uses of it as
well in due time.

Also removing the hack on innerProcess as I happened to see it and the
affected versions are now <1% users.

+# The Syncthing Goals
+
+Syncthing is a **continuous file synchronization program**. It synchronizes
+files between two or more computers. We strive to fulfill the goals below.
+The goals are listed in order of importance, the most important one being
+the first.
+
+> "Syncing files" here is precise. It means we specifically exclude things
+> that are not files - calendar items, instant messages, and so on. If those
+> are in fact stored as files on disk, they can of course be synced as
+> files.
+
+Syncthing should be:
+
+### 1. Safe From Data Loss
+
+Protecting the user's data is paramount. We take every reasonable precaution
+to avoid corrupting the user's files.
+
+> This is the overriding goal, without which synchronizing files becomes
+> pointless. This means that we do not make unsafe trade offs for the sake
+> of performance or, in some cases, even usability.
+
+### 2. Secure Against Attackers
+
+Again, protecting the user's data is paramount. Regardless of our other
+goals we must never allow the user's data to be susceptible to eavesdropping
+or modification by unauthorized parties.
+
+> This should be understood in context. It is not necessarily reasonable to
+> expect Syncthing to be resistant against well equipped state level
+> attackers. We will however do our best. Note also that this is different
+> from anonymity which is not, currently, a goal.
+
+### 3. Easy to Use
+
+Syncthing should be approachable, understandable and inclusive.
+
+> Complex concepts and maths form the base of Synchting's functionality.
+> This should nonetheless be abstracted or hidden to a degree where
+> Syncthing is usable by the general public.
+
+### 4. Automatic
+
+User interaction should be required only when absolutely necessary.
+
+> Specifically this means that changes to files are picked up without
+> prompting, conflicts are resolved without prompting and connections are
+> maintained without prompting. We only prompt the user when it is required
+> to fulfill one of the (overriding) Secure, Safe or Easy goals.
+
+### 5. Universally Available
+
+Syncthing should run on every common computer. We are mindful that the
+latest technology is not always available to any given individual.
+
+> Computers include desktops, laptops, servers, virtual machines, small
+> general purpose computers such as Raspberry Pis and, *where possible*,
+> tablets and phones. NAS appliances, toasters, cars, firearms, thermostats
+> and so on may include computing capabitilies but it is not our goal for
+> Syncthing to run smoothly on these devices.
+
+### 6. For Individuals
+
+Syncthing is primarily about empowering the individual user with safe,
+secure and easy to use file synchronization.
+
+> We acknowledge that it's also useful in an enterprise setting and include
+> functionality to support that. If this is in conflict with the
+> requirements of the individual, those will however take priority.
+
+### 7. Everything Else
+
+There are many things we care about that don't make it on to the list. It is
+fine to optimize for these values as well, as long as they are not in
+conflict with the stated goals above.
+
+> For example, performance is a thing we care about. We just don't care more
+> about it than safety, security, etc. Maintainability of the code base and
+> providing entertainment value for the maintainers are also things that
+> matter. It is understood that there are aspects of Syncthing that are
+> suboptimal or even in opposition with the goals above. However, we
+> continuously strive to align Syncthing more and more with these goals.

-This is the Syncthing project which pursues the following goals:
+## Goals
 
- 1. Define a protocol for synchronization of a folder between a number of
-    collaborating devices. This protocol should be well defined, unambiguous,
-    easily understood, free to use, efficient, secure and language neutral.
-    This is called the [Block Exchange Protocol][1].
+Syncthing is a **continuous file synchronization program**. It synchronizes
+files between two or more computers. We strive to fulfill the goals below.
+The goals are listed in order of importance, the most important one being
+the first. This is the summary version of the goal list - for more
+commentary, see the full [Goals document][13].
 
- 2. Provide the reference implementation to demonstrate the usability of
-    said protocol. This is the `syncthing` utility. We hope that
-    alternative, compatible implementations of the protocol will arise.
+Syncthing should be:
 
-The two are evolving together; the protocol is not to be considered
-stable until Syncthing 1.0 is released, at which point it is locked down
-for incompatible changes.
+1. Safe From Data Loss
+
+   Protecting the user's data is paramount. We take every reasonable
+   precaution to avoid corrupting the user's files.
+
+2. Secure Against Attackers
+

+   goals we must never allow the user's data to be susceptible to

+
+5. Universally Available

+
+   There are many things we care about that don't make it on to the list. It
