   One possible way to fix this is to make the tablet server keep all wals newer than the
oldest referenced.  So if a tserver has 4 closed WALs W1, W2, W3, W4 where W4 is the oldest
and W1, W3 are referenced then W1,W2,W3 should be kept in zookeeper.  In this case W4 can
safely be GCed, but not W2.
