Re: NSZone pointers

Just wondering... how's CoreFoundation affected by this?  CFAllocators (NSZone's equivalent) is everywhere.  Does it also get disregarded?  I've been overlooking CFAllocator for a while now, so I would prefer if it wasn't used at all, too.

Oh, and apparently I missed that in Objective-C 2 they were removed.  +allocWithZone: on OS X now apparently ignores the zone pointer and -zone always returns the default malloc() zone.
