Description

In the current implementation, the regionserver blocks new transactions from occuring when the HLog is rolled. Closing the existing HLog sometimes takes more than a few seconds and during this time all new puts/increments are blocked. It will be nice if we can continue to write new transactions to the new HLog (but maybe not commit those transactions) while the old HLog is being closed.
