For security reasons, GvR requested that Idle's Python execution server process
connect to the Idle process, which listens for the connection. Since Idle has
only one client per server, this was not a limitation.

The RPCServer handler class is expected to provide register/unregister methods.
RPCHandler inherits the mix-in class SocketIO, which provides these methods.
See the Idle run.main() docstring for further information on how this was
accomplished in Idle.

aR Handle messages received on the socket.
Some messages received may be asynchronous 'call' or 'queue' requests,
and some may be responses for other threads.
'call' requests are passed to self.localcall() with the expectation of
immediate execution, during which time the socket is not serviced.
'queue' requests are used for tasks (which may block or hang) to be
processed in a different thread. These requests are fed into
request_queue by self.localcall(). Responses to queued requests are
taken from response_queue and sent across the link with the associated
sequence numbers. Messages in the queues are (sequence_number,
request/response) tuples and code using this module removing messages
from the request_queue is responsible for returning the correct
sequence number in the response_queue.
pollresponse() will loop until a response message with the myseq
sequence number is received, and will save other responses in
self.responses and notify the owning thread.
