unless 0 is a valid content-length, which it can be. Also, what about
when we are reading something in without a know C-L, for example from an

Maybe we're attacking the problem from the wrong angle. Rather than
modifying mod_cache, modify the garbage-collector (e.g., htcacheclean).
Do a two pass cleanup.
I think it's insane that it has to traverse the directory structure to
do find the objects. There should be an index of objects. Traversing
the tree can be a huge hit on large, busy structures.
