Review request for hbase and Ryan Rawson.


Summary
-------

Test wasn't waiting until the put thread had started before it started reading, so would often fail having read 0 columns.


This addresses bug HBASE-2589.
    http://issues.apache.org/jira/browse/HBASE-2589


Diffs
-----

  src/test/java/org/apache/hadoop/hbase/regionserver/TestHRegion.java 44e7e6d 

Diff: http://review.hbase.org/r/79/diff


Testing
-------

Ran it a few times on my box locally, seems to pass now where it used to fail most of the time.


Thanks,

Todd

> IIRC we added this test in response to a bug in HBASE-2248 in the old branch. It's failing about half the time on my internal Hudson. i=36 expected:<1000> but was:<0>
