select: Yes.

WaitForSingleObject: Really? The documentation seems to say only on
events, mutexes, semaphores, processes and threads. No mention of
pipes or files. http://msdn.microsoft.com/en-us/library/bb202783.aspx
Also, presumably it would be WaitForMultipleObjects? Regardless, I'm
sure there's some way to do this. I just don't think it's obvious or
easy enough to be considered a reasonable alternative to using
threads.

Twisted: That actually looks quite nice, but pulling in Twisted isn't
always going to be a reasonable option.

I just want to be sure - the idea of removing the threading module
sounds ludicrous. It's not getting serious consideration, is it?
