Well, what I mean is that there is a time window where mailbox operation
front the frontend would succeed, but the outcome not received by the
frontend.  Example :

1. MUPDATE master down, frontend loose connection
2. MUPDATE master up again
3. frontend issue CREATE
4. backend RESERVE then CREATE succeed
5. MUA (or whatever) look for new folder, can't see it.
6. frontend reconnected to MUPDATE master
7. frontend receive update and now see new folders

I am interested in minimizing the time between 2 and 6, to avoid 5.

Thanks for your insights!
