Description

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:

assertEquals(previousKV.getValue(), thisValue);

Since this is a byte array, we should use Bytes.compareTo.
