1) Reduces overhead.  Needless thread switching is expensive; if all  
calls are non-blocking and individually cheap, there's no reason to be  
moving outgoing method calls to a secondary thread and then move  
incoming method calls back to the main thread.
2) Prevents crashiness.  http://smartcrashreports.com/dev/?q=NDRunLoopMessenger&r=all 
  shows a bunch of crashes in the intrathread messaging class... all  
of which are connected to Bonjour.  I've spent a long time in the past  
trying to figure out what's going on with these sporadic crashes, to  
no avail.
3) Code simplification
