Tellier Benoit updated MAILBOX-215:
-----------------------------------
    Attachment: MAILBOX-215-no-path-locker.patch

No path locker.

Improves Cassandra performance as several non concurrent actions can be performed simultaneously
on the same mailbox.

> In the Cassandra module, concurency is handled directly by using conditionnal updates.
>  - So we don't need locking
>  - Locking at the JVM scale makes no sens.
> So we need to introduce a "fake" path locker, that does not lock anything.
