Hi,
I'm not sure whats wrong with the BoehmGC implementation. Its fast
and efficient, it works very well, and it can be easily made
interoperable with RC (if thats really required).
Well, it looks to me like the easiest way to get something broadly
compatible with Apple's implementation. I think we need the
capability to zero weak references when the memory referenced is
GC'd though ... not sure if that's easily achieved with Boehm.
In libFoundation you would watch the object for finalization, check
+ (void)registerForFinalizationObserver:(id)observer
selector:(SEL)selector
object:(id)object
for the implementation. Its 'relatively' expensive though.
Don't know what additional features todays Boehm GC has.
Greets,
