I need more coffee before I give a coherent answer -- and I need _lots_
of it before I can comment on Ferenc's code, although that looks very
good so far.

But remember the deletion dirent node can obsolete more than one old
dirent, on NAND flash. When we GC a dirent node, we weren't able to
immediately mark the old one obsolete so there can be two. Or more, if
this keeps happening and we lose power each time we GC the node in
question.
