New submission from STINNER Victor <haypo at users.sourceforge.net>:
_multiprocessing.Connection() allows to use any positive (or nul)
number has socket handle. If you use an invalid file descriptor,
poll() method may crash (especially for big positive integer).
Example:
>>> import _multiprocessing
>>> obj = _multiprocessing.Connection(44977608)
>>> obj.poll()
Erreur de segmentation (core dumped)
Fix: use fstat() to make sure that the handle is valid. Attached patch
implements this feature.
Another solution would be to reuse code from Modules/selectmodule.c.
