Looking at the stack-trace it's probably a change to how the GIL is
managed in PyObjC 1.1 (as oposed to earlier versions). Starting from
PyObjC 1.1 we give up the GIL when calling Cocoa code (such as in
objc_NSApplicationMain when calling NSApplicationMain).
I'd be surprised if the code generated from cfsupport.pyx contains
calls to PyGILState_Acquire, which would give interesting events when
runLoopTimerCallBack is called ;)
