  OK, I stand corrected, that matches with observed behaviour. Trouble  
is just, I really wanted to override retain/release, breakpoints  
weren't really enough... and I wasn't able to find a way to tell  
CFRetain/CFRelease to call me when they do their work. Tried lots of  
things, custom allocators etc., but there seems to be some information  
missing in the retain callbacks and similar.
