> Two improvements:
> 1. I was running testWritesWhileGetting on 0.90.6 (which lacks HBASE-4195) and I couldn't
get the 20% failures mentioned in the JIRA.  It was more like 1%.  So I increased the flush
frequency and it failed most of the time.
> 2.  The check on failure is wrong:
> {code}
> assertEquals(previousKV.getValue(), thisValue);
> {code}
> Since this is a byte array, we should use Bytes.compareTo.
