Well, they have other methods. Such as their "I/O Completion Ports",
which I've seen easily handle 30-40,000 sockets (IIRC that's the number
- it was at least very large)... But they do like to do things their own
way...

If you're talking win32 port specific, I think it was the other way
around. Using select() *prevents* catching signals with the current
implementation. This is why we need the "select replacement", see my
latest patch.
