Yeah, I figured fileno() probably wouldn't be news to you. I don't
suppose there's anything convenient in the rest of your application
that makes such a list/dict plausible? For instance, if you need to
maintain a list of all current socket connections to support broadcast
operations, then it's not much harder to also maintain the fd->socket
mapping.
