I think you forgot to call 'accept' in a loop, which returns a new socket
for each connection, and then start a new thread for each one.

For a concrete, working example see
http://wiki.rubygarden.org/Ruby/page/show/SingletonTutorial
and scroll down to where it says "class Pop3Server"

For general information on threads see

HTH,
