-----------------------------------------------------------------
Nope, tests are now crashing and burning.
EDIT1:
test/conf/cassandra.yaml was still using global memtable settings, so that was
the first error.
Now it's complaining that KSMetaData.deflate() isn't defined, which is broken.

> This is particularly useful in the scenario where you have a few CFs with a
> high volume of overwrite operations; increasing the memtable size/op count
> means that you can do the overwrite in memory before it ever hits disk. Once
> on disk compaction is much more work for the system.
> But, you don't want to give _all_ your CFs that high of a threshold because
> the memory is better used elsewhere, and because it makes commitlog replay
> unnecessarily painful.
