In Linux, you can open the socket before forking and then use it in
the child processes; there is also a way to pass open sockets from one
process to another, but the Python lib currently does not support that
feature.  It's worth adding and there's an open RFE for it, but it
hasn't been important enough that anyone's bothered coding it so far.
