	A) You must Disable() to play with this list (and have a pretty damn
	   good reason for doing so!)
	B) Exec (and it's lists) was written before there were
	   SignalSemaphores in the system, so it's stuck with locking methods
	   used in the initial implementation (usually Forbid()).  Unfortunate
	   but unavoidable.
