I compare Coda more with squid than with NFS, and hope that at some
point it will be normal to run with a 6GB venus.cache.

It would affect the way files are placed in venus.cache. If the option
is changeable between restarts without reinitializing venus, we would
have to tear down/rebuild the hierarchical layout of venus.cache. I'm
guessing that is too much effort for a 'one-time' optimization.

We could modify some benchmark app that can measure the difference so
that we can decide on the 'optimal' layout before starting the client.
f.i. modify the postmark benchmark to compare a run in a hierarchical
tree vs. a flat directory layout.
