Work is broken up into a series of stages.
- ReadStage - performing a local read.
- RequestResponseStage - handling responses from other nodes.
- MutationStage - performing a local write.
- ReplicateOnWriteStage - for counter writes, replicates after a local write
- GossipStage - handles gossip

It would be very useful to be able to get refreshing statistics from tpstats, a
la top.
nodetool -h localhost tpstats [n]
refresh every second, show me the Active and Pending and Blocked columns as
they currently exist, but under Completed show me a per-second rate based on
the delta from the
