Sockets and messaging services

[Stephen]

I have a CGI script which takes a HTTP request then sends
a message to a custom server built on top of SocketServer.ThreadingTCPServer.
Not that there is much chance of webserver CGI saturating the latter, 
but does Python have a messaging framework, similar to JMS for Java ?

Also in testing my socket server, I have noticed that if a process 
opens a socket (S) and the process is destroyed before closing the 
socket (S.close()), then the socket server gives an error 
"error: (10054, 'Connection reset by peer')". 
What happens with the server threads that were handling the sockets ?
(I am using SocketServer.ThreadingTCPServer)
