Additional info:
There doesn't seem to be anything useful in the daemon output by default.  I've
added debug statements in various places to try and understand what's going on.
 I'll elaborate in future comments when I can better organize what I'm seeing. 
Just wanted to get this out there incase it's something obvious :)
