Hi all,
Remember though that NSZombieEnabled does not work with toll free
bridged classes like NSString, for those you need CFZombieLevel. See:
<
http://www.cocoadev.com/index.pl?NSZombieEnabled>
This seems to be a little known fact. It seems to me that _no one_ uses
CFZombieLevel. :( I implore you to turn it on, and try your apps with
it. Technote 2124 (<
http://developer.apple.com/technotes/tn2004/
tn2124.html>) has some details, but the short version is: in terminal type:
export CFZombieLevel=65537
open /path/to/app
QuickTime Player, iTunes, Safari, and probably many others crash _at
launch_ when this is turned on.
I really wish CFZombieLevel and friends were enabled by default by Xcode
for Debug targets. Off to Radar I guess.

I don't think there's a bug in CFStringHash :)
