> Asking a tablet server to split a tablet can result in an unbalanced load.  When the
balancer runs, it returns a plan to move the tablets. The next run of the state machine will
send unload messages to tablet servers.  This, in turn, will result in waking up the master
to re-run the state machine.  In this way, the master ends up queuing many requests to unload
a tablet.  Eventually the tablet server will unload the tablet and then complain about being
asked to unload a tablet that is no longer loaded.
