> cache saving seems to be broken in 1.0.2 and 1.0.3 i have 2 CF in keyspace

> in second test system i created these 2 column families and none of them got
> single cache key saved. Both have save period 30 seoonds - their cache should
> save often. Its not that standard column family works while super does not.

> If this is done on purpose for example cassandra 1.0 is doing some heuristic
> decision if cache should be saved or not then it should be removed. Saving
> cache is fast.
