btw, Cog is suspectible to have bugs if during run time you will
change a class to be no longer compact or
(and then installing a different class to be compact on same compact
classes array index as before).

To avoid that, there should be a primitive which should refresh
compact indices for most used classes,
to avoid bugs.

(The StackInterpreter>>checkAssumedCompactClasses should be run each
time when some class become (un)compact).
