What I would like to see is a module that provides a low-level API
for doing cross-platform asynchronous IO.  The two necessary parts

    * a wrapper that allows non-blocking reads and writes on
      channels (sockets, file descriptors, serial ports, etc) 

    * a select() or epoll like interface that allows waiting on
      multiple channels

The implementation requires some intricate and platform specific
code which is why it would be nice to be a standard library feature.

I'm sure that Twisted has the necessary parts but the problem, IMHO,
is that it does so much more else.
