The wonderful Technical Note TN2124 "Mac OS X Debugging Magic"
unfortunately says absolutely nothing about garbage collection.


At the risk of angering the Gods of documented APIs:

~ % strings /usr/lib/libobjc.dylib /usr/lib/libauto.dylib | grep '^AUTO'
AUTO_ENABLE_MONITOR
AUTO_ENABLE_MONITOR=YES
AUTO_DISABLE_GENERATIONAL
AUTO_LOG_NOISY
AUTO_LOG_ALL
AUTO_LOG_COLLECTIONS
AUTO_LOG_REGIONS
AUTO_LOG_UNUSUAL
AUTO_LOG_WEAK
AUTO_COLLECTION_THRESHOLD
AUTO_COLLECTION_RATIO
AUTO_RECORD_REFCOUNT_STACKS
AUTO_DIRTY_ALL_DELETED
AUTO_USE_EXACT_SCANNING

They may not help you with tracking down zombies, and they may go away in future releases, but I certainly found them useful when profiling a GC app.
