Windows has I/O Completion Ports. Basically: you associate your
sockets with a completion port, then you make a thread pool to
retrieve results from the completion port. It is fairly simple to
wrap this so you recieve a callback once an operation is complete.
I don't think this maps very well to your API... perhaps we can
discuss this further to make sure both platforms perform efficiently.
I'll be gone today but will write up some basic code for you to get
the idea of how IOCP handles sockets.

They aren't similar. Platforms will need seperate wrappers.
