* Implementation of the Manager interface that makes use of
* a Store to swap active Sessions to disk. It can be configured to
* achieve several different goals:
*
* Persist sessions across restarts of the Container
* Fault tolerance, keep sessions backed up on disk to allow
* recovery in the event of unplanned restarts.
* Limit the number of active sessions kept in memory by
* swapping less active sessions out to disk.
