Hi,
you only have to avoid closing the connection after your first 
request/response pair, which you would otherwise do by calling 
self.transport.loseConnection() in your protocol. Twisted doesn't make 
that decision for you. Of course it also depends on the server/protocol 
supporting it.

Then there's a project called txconnpool at 
http://pypi.python.org/pypi/txconnpool, maybe it does what you want.

Johann
