I don't have a strong opinion on this either. The distinction between
send() and send_all() makes sense to me though (send_all() works hard to
get all your data out, send() only does what it can quickly).

Personally for calls like select() I think returning early on EINTR makes
sense, it's usually part of a select loop anyway.

The only thing I care deeply about is that you shouldn't restart anything
before letting a Python-level signal handler run. A program might well have
a Python signal handler that must run before the I/O is restarted, and the
signal handler might raise an exception (like the default SIGINT handler,
which raises KeyboardInterrupt).
