There is a very small, and very old, window for a race in the socket

This issue would appear to exist since its (linux_close.c) creation
back in 1.4, but since the window for the race is tiny, it seems to
have gone unnoticed until now.
I think at the time that close would block if there was another thread
doing I/O so this may be why the signal was queued first.
The proposed change looks good to me.
