0.96.0 keep logging "Memstore is above high water mark"
While running PE with 10 clients, server keep logging:
2013-09-02 14:56:59,919 WARN  [RpcServer.handler=5,port=44439]
regionserver.MemStoreFlusher: Memstore is above high water mark and
block 2362ms
2013-09-02 14:56:59,919 WARN  [RpcServer.handler=18,port=44439]
regionserver.MemStoreFlusher: Memstore is above high water mark and
block 2363ms

Then when test is over:
2013-09-02 14:57:02,280 WARN

I guess it's only because of PE, but is this something which need to
be looked at?
