Agreed, async is the natural way to do socket i/o. Like you say its trivial to
implement blocking functionality on top of non-blocking, and a lot less trivial
than doing it the other way around.

If you have oneway RPC's, why would it be difficult to build messaging on top of
that? The two seem to me to be almost the same thing.
