Yeah, Jonas.  We can't reasonably expect any behavior from the garbage
collectors.  I can't think of any other precedent for this.  And as
collectors become more complicated, doing a gc that catches _every_ piece of
garbage is becoming harder or even impossible (not aware of any GC's where
it is "impossible" in specific cases, but it wouldn't surprise me).  The v8
guys simply won't let us do this.  :-)

And saying that at the worst case your setVersion transaction will stall
possibly forever just doesn't seem like a good solution either.

What if we made the default for onsetversion to be calling close?  I.e.
instead of the close behavior being opt-out, it'd be opt-in?  I know we made
a conscious decision originally of it being opt-in, but I don't see how
that'll work.
