call rt_finalize(p, true) (det means "deterministic", and is called when you do "delete p" for example).  The collectHandler is called when the GC finalizes something.  If the collectHandler returns false then the object's dtor will not be invoked.  So basically, collectHandler is a hook for reporting GC finalization of objects and can also affect whether the dtor is invoked by the GC for specific objects.
