[New-bugs-announce] [issue9950] socket.sendall() crash when receiving a signal

New submission from Antoine Pitrou <pitrou at free.fr>:

This was introduced by r74426 which addressed issue1628205. socket.sendall() calls PyErr_CheckSignals() (and potentially returns to the caller) without having the GIL.

>>> import socket
>>> c, s = socket.socketpair()
>>> s.sendall(b"x"*(100 * 1024**2))
