: If a thread has a hold on a vm_object and enters hold_wait (via either
: vm_object_terminate or vm_object_collapse), it will wait forever for the hold
: count to hit 0. Record the threads holding an object in a per-object array.
Hmm. That's a bit iffy, it is possible for there to be more than 32
holds on a VM object.
