I haven't gotten around doing a release of the current state yet.

PyObjC does not support GC.

The expand on that:

* AFAIK Python is not build correctly to link into GC enabled  
applications

* While I try to ensure that PyObjC's reference management is safe  
w.r.t. GC (using CFRetain/CFRelease rather than -retain/-release) I  
have never tested if this is sufficient. That means PyObjC is almost  
certainly unsafe w.r.t. GC.
