Certainly, we don't want to to use the savannah server for `annotate'
nor for other VC operations that can be performed locally.

If some people start using lightweight checkouts, a few simultaneous
`log' and `annotate' can bring the server's CPU to its knees. I'll vote
for disabling those operations on the server, if possible.

BTW, how well does concurrency the smart server? It blocks writes when a
read operation is performed?
