>   * insert 5,000 records in a single columnfamily with UUID keys and
> random string values (between 1 and 1000 chars) in 5 different columns
> spanning two different supercolumns
>   * delete all the data by iterating over the rows with
> get_range_slices(ONE) and calling remove(QUORUM) on each row id
> returned (path containing only columnfamily)
>   * count number of non-tombstone rows by iterating over the rows
> with get_range_slices(ONE) and testing data.  Break if not zero.

> while this is running, call "bin/nodetool -h localhost -p 8081 flush KeySpace" in the background every minute or so.  When the data hits some critical size, the loop will break.
