Oops.  I knew that.  Some kind of weak reference would be handy
though.  (ets tables just jumped to mind because of familiarity with a
few lisp/scheme implementations of weak-reference hash-tables).

Hmmm.  Maybe a per-process table: put_weak and get_weak?

Oh well.  It's not so important.  Weak-references have always struck
me as rather a kludge anyway (but a useful kludge, for a certain
subset of problems).
