    I'm a little nervous about decreasing the data pool that much. It might be 
wise to do some testing before decreasing it to 5.

>
> + Create an event loop group for each client-server pair (data, client and 
> user)
> + Allow DrillClient constructor to specify an event loop group (so user event 
> loop can be used for queries from Web API calls). Deprecate old DrillClient 
> constructors and create a helper class to build instances.
> Miscellaneous:
> + Move WorkEventBus from exec/rpc/control to exec/work
