------------------------------------------------

I am just seeing v2. Now it is accessed in a different way.
bq.The reason why I use a PriorityQueue here is because the sync with a higher 
txid may come first as we do this in HRegion.put
Correct. I agree to use PriorityQueue. But just was checking cases where all it 
could go wrong. 
Even now there is no synchronization. So you expect the remove/add to work 
correctly?

> Found this when addressing HBASE-16890. It is one of the possible reason that
