I've had a few nodes crash (Out of heap), and when I pull the heap dump, there 
are hundreds of thousands of MessageDeserializationTasks in the thread pool 
executor, using up GB of the heap. I'm running 0.6.2 on sun jvm u20 and the 
nodes are under heavy load. Has anyone else run into this? I haven't deeply 
understood the deserilization pool, but just based on the name, it seems like 
it should be super fast. What could make it back up with hundreds of thousands 
of messages?
