[issue25942] subprocess.call SIGKILLs too liberally

Mike Pomraning added the comment:
If I understand correctly, the _try_wait mechanics (or 3.5's syscall behavior) already handle EINTR the way we way: ignore it and try wait()ing again.
So, this patch would kill only on a timeout, and never on another error like Ctrl-C, a UserDefinedTimeoutException from a signal handler, etc.
That's probably the lesser of two evils, the other being a SIGKILL against an arbitrary child process. Better to document that a non-timeout-parameter interruption to subprocess.call will separate the parent from its child, than to hard kill arbitrary programs when a polite SIGINT was intended.
