> Here the CreateTable() call has arrived to the master before the tservers
> have finished initializing, and thus before they have heartbeated to the
> master.
> We should modify the start_cluster() call to wait until the tservers are
> initialized. Possibly this means adding --server_dump_info_path=... to the
> command line arguments and waiting for the file to show up. Or maybe that's
> insufficient and we should also query the master for the list of tservers.
> Either way, we need to wait a little longer in case the tservers are slow to
> start.
