> In Heron each bolt/spout instance runs in a separate JVM instance.  This reduces the failure domain for each bolt/spout to itself, and also would allow for finer grained measurements of resource usage, which would be very useful in resource aware scheduling and elasticity. 
> We should explore what performance impact this might have on storm, and what it would take to truly support it.
