Hmm, you are right.  I first have thought about this behavior as a
feature, but I now see that it is in fact not wanted.  The order the
weak vectors are processed in affects the result, which is not good,
obviously.

Right now, I hope to get around this by repeatedly scanning all weak
vectors until no new markings have taken place, and only then remove
the unmarked items.

Thanks for pointing this out!
