I tried the same thing with an NSString, and with CFZombieLevel

I got were bad access exceptions.
NSString * string = [[NSString alloc] initWithFormat:@"String %
d", 12];
[string release];
[string length];
Should I have expected this?
Yes. Class cluster objects toll-free bridged to CoreFoundation
structures are never zombified; even with NSZombieEnabled set they
will always be released.
Huh - I had misunderstood <http://developer.apple.com/technotes/
tn2004/tn2124.html>, then. It implied to me that CFZombieLevel would
have caught misbehaviors in CF objects, even if they were toll free
bridged. Of course, it contains little enough text that I was
reading a bit more into it than strictly implied.
Doc bug filed.
