-----------------------------------------
Adding to JMX would also make sense imo (less familiar with the security
support there though)
> Add l4w command "snap" to trigger log rotation and snapshotting

> "snap" command can be used to trigger log rotate and snapshotting on each
> server.
> One use case for this command is to make server restart faster by issuing
> snap command before restarting the server. This help when txnlog is large
> (due to txn size or number of txn)
> snap is a blocking command, it will return when snapshot is written to disk.
> So it is safe to call this prior to restarting the server.
