Description

If I understood the iterator transformations introduced by CASSANDRA-9975 correctly, ReadCommand.CheckForAbort should apply itself before returning a partition. At the moment it is applied to row iterators for single command partitions, but for range queries I think it only monitors the query progress when a new partition is iterated, not when a new row is iterated. So for large partitions, we may fail to log a query as slow, or fail to abort it if the RPC timeout is exceeded.
