> HRegion.ICV gets a row lock then gets a newScanner lock.
> HRegion.close gets a newScanner lock, slitCloseLock and finally waits for all
> row locks to finish.
> If the ICV got the row lock and then close got the newScannerLock, both end
> up waiting on the other. This was introduced when Get became a Scan.
> Stack thinks we can get rid of the newScannerLock in close since we
> setClosing to true.
