In the current implementation, for every shitemid that is constructed, all drives are queried and their paths are canonicalized, which is a lot of
disk
i/o and string copying. Unixfs is really painfully slow. I guess we need
some
caching scheme, but if you don't like the current one, I'll give it some
more
thought.
Can't we just invalidate the cache if we notice things have changed?
