Lars Hofhansl commented on HBASE-5782:
--------------------------------------

So the problem is that logSyncerThread keeps the edit in order but the syncer 
then applies the pending batches potentially out of order?

We might just need a "sync lock" to prevent two threads syncing at the same 
time. This is different from the update lock, which also prevents writing any 
edits.
