I think the word "cache" itself implies a storage that can get stale.

Right. Even if there's a cache mechanism, I'd very much like to see its 
invalidation by automatic means (via file-notify, or similar), at least 
by default.

Anyway, I'd prefer to implement as many operations as feasible without 
needing that cache. If the search through the project tree spends an 
order of magnitude more time searching than listing the files, there's 
not point in caching the latter.
