[issue18885] handle EINTR in the stdlib

[Guido van Rossum]

Guido van Rossum added the comment:

I wouldn't call that "being the most careful".  I've always had an implicit understanding that calls with timeouts may, for whatever reason, return sooner than requested (or later!), and the most careful approach is to re-check the clock again.
