[issue33021] Some fstat() calls do not release the GIL, possibly hanging all threads

Re: backporting this. I think backporting to 3.6/3.7 makes a lot of sense - bugfix and prerelease respectively.

For 2.7, this bug has been around for ages, the patch is small, and I have no objection - but the RM has already said no, so I guess not happening :).

That said, if I was analyzing this from scratch I'd look at the pypi download stats to assess what footprint 2.7 still has, and whether taking this fix there would make objective sense.

While it is a genuine bug - and a nice catch - I have to say that running any Python with mmapped data off of NFS is a supremely bad idea :).
