Actually it is because the servers are pretty slow on the many directory
operations. The bandwidth estimation is influenced by the slow server
responses and the client kicks in write-disconnected mode. Reintegration
is actually more efficient even for the servers, because we need only
one RVM transaction for all operations instead of a transaction for each
single operation. So this backing off both unloads the servers, and
makes server-side processing more efficient.

The problem is that while a client is write-disconnected it has more
chances of getting some inconsitent state, and there is a higher
likelyhood of hitting obscure bugs.

'cfs strong' makes the client ignore bandwidth estimates, so it should
in most normal situations keep the client in connected mode.

Then you could still be hitting the file limit, Coda assumes an average
of 24KB per file, so a 300MB cache maxes out around 12000 files.
