9de06f62ee Use Python executors instead of pools 
ProcessPool/ThreadPool don't have the ability to notice when a child worker
was terminated. ProcessPoolExecutor and ThreadPoolExecutor do notice and
provide better error messages.

Add tests to check.

c75ff4687a Turning on Ghostscript interpolation changes this test 
Seems acceptable. We don't normally use Ghostscript to downsample PDFs
like is happening in this test.

cd49e70154 ghostscript: force interpolation when rendering (#855) 
Specifying option --oversample tends to introduce upsampling in rendering
by rasterizing page to an higher DPI.

This upsampling improves OCR results, but a correct choice of interpolation
method can increase even more the OCR quality.

Ghostscript seems to use a nearest interpolation as default choice for pdf.
This method doesn't average new introduced pixels with original pixels
resulting in an almost similar image but with more pixels.

Providing -dInterpolateControl=-1 force switching interpolation on.

In this commit the above option is passed to all ghostscript rendering
calls.

After testing, rendering a page at same DPI with interpolation
enabled does not introduce significant time overhead.

4634b20de5 Raise max-image-mpixels again 
PDFs are quite likely to have a lot of pixels, e.g. large high resolution scans.
250 MP is a page of A0 sized paper scanned at 400 DPI,
should be enough in most cases.
