[Python 2.4/2.5] subprocess module is sorely deficient?

Nick is correct. The subproces tries to work around the issues with
threads. But it's no more than an ugly workaround fir Windows' short
comings on async file IO. It's a shame Windows implements the select()
syscall in wsock32 and limits its usage to sockets.

By the way I'm willing to dedicate some time to help enhancing the
subprocess. Everybody is invited to submit patches and I'll review and
check them into the trunk and py3k ASAP. Any help is appreciated:
enhancements for async IO, doc updates, more examples ...
