Fix TestHRegion.testWritesWhileScanning to not be flaky
Review Request #79 - Created May 23, 2010 and submitted
Test wasn't waiting until the put thread had started before it started reading, so would often fail having read 0 columns.
Ran it a few times on my box locally, seems to pass now where it used to fail most of the time.
Switched to a short Thread.sleep instead. Also got rid of the accessor, since I'm only accessing that variable internally.
