In general I like this but the double setting of OBJ_DEAD does make it harder to detect things like double frees.

Untangle multiple OBJ_DEAD sets.

Redo the patch back to the initial variant. Note that there is only one place that calls vm_object_terminate_dead(), so it costs nothing to set OBJ_DEAD flag there and make vm_object_terminate() to expect OBJ_DEAD is already set.

This is cleaner IMO, since both terminate_dead and terminate really not needed.
