Level 1 PostScript interpreters didn't have garbage collection...that's why
the save/restore ritual mattered so much.  There's nothing to say that
they *couldn't* have had garbage collection, but just that none of them
[as far as I know] *did* have it.

Even in Level 2, it's not clear that the garbage collectors will be capable
of compaction.  This might make a difference in LISP-like memory usage.
