Cool.  I didn't realize one could wrap a native win32 pipe
handle in some way that will work with ruby's select!

The impression I got from the windows select() documentation
was that it only works with winsock sockets.

This makes me wonder why ruby wouldn't already be creating
the "proper kind" of pipes and socketpairs that work with its
select(), if it's that easy to create one myself and wrap it
in a ruby IO object?

Strange . . .
