I note that the present code spawns the subprocess first, then opens a
socket, commenting that this is to avoid passing the open socket on to
the subprocess. Does this matter? In order to tell the subprocess
which port to listen to, we'd need to open the socket first. I don't
really know a whole lot about sockets, but from what I can tell, it
sounds like preventing a subprocess from inheriting a socket is quite
platform-dependent.

I'm certainly interested enough to give it a go, but I don't know a
whole lot about Python development. I have managed (I think) to sync
up and build a copy of trunk using Visual C++ Express 2008. I'm not
really sure about how to make patches, but I'm not going to worry
about that until I have actually made any useful changes.
