For the moment, I disabled the build time tests in skimage completely
because of #849196, to ensure it migrates before the freeze (I took the
really latest chance to do so). Therefore, I would not touch the package
before Jan 5. Once it is in testing, It would be however very important
to re-enable the tests, since this is more a crude hack than a clean
solution.

Unfortunately, I am not familar with the skimage code (I just did the
firefighter job here); specifically I don't know where to switch off
parallel tests, and what other implications that has. Maybe, you discuss
this with Yaroslav (in Cc), who is the skimage package maintainer? Also
the parallel bug I opened on the "scikit-image" github (referenced on
the numpy issue) may help there. Finally, Yaroslav should decide here.

I personally however would much more prefer to go back to the latest
numpy 1.11 in testing, and update only after 1.12 is released. I very
dislike having workarounds because a beta or a release candidate
uploaded to testing is buggy. And I would also prefer not to have a beta
or RC shipped with Stretch.

Best regards

Ole
