Michael Greene commented on CASSANDRA-275:
------------------------------------------
The freezing/defreezing of maps in RowMutation is incorrect in the patch, so
that should be left out if portions are committed.
> Replace Map.keySet by more efficient Map.entrySet

> When you iterates over all key-values of a Map is better to use entrySet()
> instead of a call to entryKey() and a call to get() inside the loop. It's
> more efficient.
> I've seen a patch like this before, but I don't think it was applied at all.
