[Twisted-Python] How do I make a Twisted server 'look' like it's synchronous?

[Victor Ng]

I'm pretty confused with how to write an XMLRPC method that runs for a 
long time.  For example - I have an XMLRPC call that will do a database 
fetch.

What do I need to do with the xmlrpc.Handler?

I've taken a look at the unit tests, but there's no sample code that 
actually uses Handler.
