Use reactor.callFromThread if you have code running in a non-reactor 
thread and you want it to initiate some action in the reactor thread.

So, if publisher.sendMessage is using Twisted APIs or otherwise requires 
that it be run only in the reactor thread, and you need to use it from a 
non-reactor thread, then use reactor.callFromThread.  Otherwise, don't.
