CFSocket notifications, (theoretical) Carbon runloop support, etc.  I 
wrote it in Pyrex after a huge waste of time trying to get it to work 
reliably in ctypes (callbacks would eventually start jumping to random 
locations in memory under load, core dump on uncaught exceptions, 
etc... I think it could be a libffi issue), and I didn't want to go 
through the same ordeal with PyObjC's callbacks after my last failed 
attempt to do Rendezvous callbacks with it.  The Pyrex module was not 
hard to write, and my wrapper does take a  CFRunLoopRef from a PyObjC 
NSRunLoop if you're trying to integrate it with Cocoa or whatever.
