i agree that the lots-of-small-files case will still suffer
(mainly because the non-hierarchical mount table
means we can't know what's mounted below a particular
node without asking the server).

but this still gives the opportunity to considerably speed
up many common actions (e.g. {walk, open, read, close})
without adding too much (i think) complexity of the protocol.

also, as david leimbach points out, this case is still amenable to the
"send several
requests concurrently" approach.
