> Ted ran into this in cluster testing. If the largest region is unflushable
> (eg it's in the midst of closing during a split, and hence doing its own
> flush), the global memstore pressure code doesn't notice this. So, it keeps
> trying to flush it, and ignores the false return code from flushRegion.
> Instead, we should iterate down the list of regions and keep trying to flush
> them until we find one that works.
