Yes.

The other problem is that SwitchPoint.gWT can be made fast but
it's harder to get the same speed if someone uses 
SwitchPoint.hasBeenInvalidated
in a fast path.
We really don't want bug reports saying that hasBeenInvalidated is dead slow
forcing VM implementers to find a way to optimize hasBeenInvalidated
knowing that SwitchPoint.gWT is the way to go.
