yeah, this is mostly about other stuff being added in-between later on.
probably not too likely in this case, but I always prefer setting a
cleanup-potentially-required flag *before* doing the thing that
potentially requires cleanup, rather than after (even if the current
code does everything right). it's the safer variant (even though it of
course also has potential for stuff being added in-between, and then
triggering cleanup without the cleanup-source actually having happened
;))
