	You are right.  I misunderstood the original question slightly.

	Ok, the real need here is to purge the relocatable block and
	set the master pointer to nil.  This should be possible as
	follows:

		HUnlock(H);		{ can't be locked		}
		EmptyHandle(H);		{ IM II-40			}
		LoadResource(H);	{ gets it back from disk	}
