Gah. Calling malloc_create_zone followed by malloc_zone_register of said zone is causing the problem. Omitting the register seems to work fine and doesn't cause the hang. Is this legit? Are you not supposed to register a zone after creation? The comments in malloc/malloc.h say that malloc_zone_register "regisers a freshly created zone; should typically be called after a zone has been created". Or this function only for zones you're building from scratch (i.e., filling out the structs)?

From Google [I haven't bothered to actually download the darwin- source for malloc to make sure], but malloc_create_zone() calls malloc_zone_register() on the zone before returning. Given the lack of documentation, I would postulate that you should only call malloc_zone_register() for a zone that you somehow create yourself, without the use of malloc_create_zone().
