I agree with you here.

For now it's just an improvement that speeds up things in a corner case
of largefiles. It definitely needs more refactoring because it is rather
"hacky". This said, fncachestore (or maybe even basicstore) should IMHO
be extended so that one can at least query the mere existance of files
in less than O(log(n)) without crawling all the files in store by
calling datafiles() or even walking through the files in store.

Cheers!
