[3.6] bpo-33021: Release the GIL during fstat() calls (GH-6019) (GH-6160)
fstat may block for long time if the file descriptor is on a
non-responsive NFS server, hanging all threads. Most fstat() calls are
handled by _Py_fstat(), releasing the GIL internally, but but
_Py_fstat_noraise() does not release the GIL, and most calls release the
GIL explicitly around it.
This patch fixes last 2 calls to _Py_fstat_no_raise(), avoiding hangs
when calling:
- mmap.mmap()
- os.urandom()
- random.seed()
(cherry picked from commit 4484f9dca9149da135bbae035f10a50d20d1cbbb)
