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

    Attachment: CASSANDRA-2147.patch

now (also -r flag wasn't parsed correctly, which is fixed too).

> This can be observed by watching how much the row/key cache grows on each 
> run.  I'm not sure when this started or if it was always the case, but it's 
> actually useful behavior when you want to benchmark just the cache, so it'd 
> be nice to preserve as an option.
