(Likely fixes other bugs as well.) When a cmirror client timed out waiting for a response from the server, it would send the request again. Sometimes, the server simply took to long to get back to the client... it would then develop an off-by-one error - responding to the first _and_ the second request. The client could then be asking to mark a region, and recieve a response for a previous request. This has the potential to cause many problems. Sequence numbers have been added to fix the problem.
