Thanks for the response, Andreas.  I've done as you said and provided 
Qt.QueuedConnection as the final parameter to my connect() calls and it 
doesn't seem to work, but there may be some other problem because now 
I'm seeing a segfault that I wasn't seeing before. :)

Does it matter when the signal connections are made, i.e. does it matter 
if they are made before or after the background threads are created?
