[Python-Dev] Adding poll() system call

[Jeremy Hylton]

If we're adding poll to enhance scalability, I'd like to see a more
efficient interface that generates the poll_fd* separately from
calling poll.

The interface would be something like this:

obj = poll.new() # generate a new pollfd array
obj.register(f1, POLLIN | POLLOUT)
obj.register(f2, POLLOUT)
obj.poll()
obj.unregister(f2)
obj.poll()

I think this would be a lot more efficient when the files being polled
don't change very often.
