Yeah, and it's still not documented ....

When I talked with Mark about this, I seem to recall that he indicated 
that in WASD the worker process never read from the socket, just wrote 
to it.

My preference would be to have the listener grant the connection, and 
then hand the socket off to a worker process for all communications.

Steve thinks I should use the Aux Process capability in TCP/IP.  I'd 
rather create my own processes.

And it's still not documented, that I've been able to find ....
