I, however, see no reason why we need to do so, since we are now locked
during the whole deletion (which wasn't necessarily true before).  I
propose a simplification in which we delete it only when there is no
more going back, so we don't need to add it again.

Ok lets hope that holding the lock does not cause issues.

BTW: One of the good things about this set, is that we are naturally
exercising cache destruction a lot more than we did before. So if there
is any problem, either with this or anything related to cache
destruction, it should at least show up a lot more frequently. So far,
this does not seem to cause any problems.
