There are three options.  Twisted (http://www.twistedmatrix.com/)
uses a single process.  Many web servers fork new processes to
handle incoming requests.  Threads are another option.  Each has
benefits and drawbacks.

The MU* server I'm developing has a single thread dedicated to
handling sockets, using a select() and handle loop, giving me the
benefits of both single-process and threaded implementation.

I would suggest familiarizing yourself with how to build (and
possibly program) within several different types of mud servers.
You don't have to be great at it, but I've found that knowing how to
build inside the mud helps you to understand some of the design of
the mud's internals, as well as concepts like inheritance and the
importance of navigable code.  ("You are in a maze of twisty little
passages, all alike.")

Also, as mentioned before, do some back-reading within the archives
on kanga.nu to see if some of your current questions, spoken or
unspoke, have been asked before.
