no, what I am working is rather the opposite: the current implementation
uses exclusive locks on mailboxes where it could do away with a shared
read-only lock. That's because the Cyrus DB API currently does not
support shared locks.
We want to reduce latency of requests, and that's what I am optimizing
for. The work only touches the twoskip backend and is only for certain
hot-paths in the code.
