> sstablescrub has Xmx hardcoded to 256MB.  This is not enough in my installation and causes an OOM.
> Since it's meant to be run offline, the memory usually allocated to the daemon can be safely given to the tool.
> Attached is a patch that makes it respect $MAX_HEAP_SIZE (with fallback to 256MB if not defined)
