That is blocking code and is not suitable for usage in a Twisted server 
if you expect good performance.  All functions that run in the 
reactor's thread should be designed to return quickly so that Twisted 
can handle events quickly.  You either need to refactor it to run 
iteratively (via successive callLater, LoopingCall, etc.), or in 
another thread (deferToThread).
