Ok. Let me try to get this straight :-)
Since we *only* permit signals during the select() call, we are safe as
long as we don't call select() inside the signal handlers? (since
select() is not on the list of safe functions). Which we don't.
That makes sense :-)
If that is indeed the case, I withdraw all my comments and misdirected
ideas, and say we go for a win32 specific workaround :-)
