In the plain Threaded AppServer, each thread is responsible for picking
up a request, receiving the request from the network, running it through
the Application, and then sending the response.  The issue is that for
clients with slow connection, the Threads could easily get bogged down
in doing network IO.

In the Async version, the threads are only responsible for running the
request through Application.  The main network thread uses the asyncore
module to handle all network IO from one thread.  Network communication
is mostly a matter of waiting.  So the asyncore module switches quickly
between sockets sending and receiving on the sockets are ready.  Much
more efficient.
