Re: class gc

This is what we do right now.  That's because the Boehm collector is
smart about this sort of thing, though -- not from any real plan.

Not all class objects are in the data section.  Classes representing
array objects are allocated on the heap.

Presumably we'll deal with this somehow when we do the next round of
GC work.  I don't know when that will be.

FWIW it's possible that more things will be moved into the data
section.  For instance some arrays could be put there.
