---------------------------------

    Fix Version/s:     (was: 0.94.0)
                   0.96.0

Moving out of 0.96 for (although this would be a good performance improvement, so pull back
if you want to work on it)

> As servers get beefier, it makes less and less sense to have only a single thread do
flushes at a time. In watching an insert-only benchmark run, HBase isn't currently disk, network,
or CPU-bound -- it seems it's bound only by the rate at which flushes and compactions get
processed. Increasing the threading a bit here should increase total disk/network throughput
utilization.
