That's a terrific idea.  The penalty may not even have a noticable
effect.  The table is only checked once per time a method is compiled,
as far as I can remember.  A different mechanism is used when restricted
classes decide which methods may be invoked.

I'm still dying to know why PrivilageMtehods.cs *failed*.  It's a short
changeset, though, so duplicating it to use the above technique
shouldn't take tooooo long.
