> To increase the probability of snapshots succeeding, we should attempt to
> prevent splits and region moves from happening. Currently we take region
> locks but this could be "too late" and results in an aborted snapshot.
> We should probably take the table lock (0.96) when starting a snapshot and
> for a 0.94 backport we should probably disable the balancer.
> This will probably not be tackled until after trunk merge.
