Message 137631 - Python tracker

Actually, it's part of a more general problem with EINTR being returned by many posix/socket module functions, see for example issue #7978.
On the one hand, having to retry manually on EINTR is cumbersome, on the other hand, some code might rely on this - receiving EINTR - and the posix module policy is to expose syscalls as-is.
This should probably be closed as duplicate of issue #9867.
