[issue23863] Fix EINTR Socket Module issues in 2.7

[Jeff McNeil]

Jeff McNeil added the comment:

So, yeah, that's right. In the attached patch, I'm closing the file descriptor if the timeout/error happens on a non-blocking call.  It fails with an EBADF on reconnect at that point, but it doesn't potentially leave an FD in the proc's file table.

Should be no more EINTR's coming out of the select call.
