Oh, I have been forgotten TOPOLOGY_SHELLBOLT_MAX_PENDING when creating this
PR.
I agree that we would be fine with TOPOLOGY_SHELLBOLT_MAX_PENDING since it
guarantees count of pending tuples with blocking manner, and finally ABP would
be triggered when subprocess couldn't handle tuples as fast as it flows.
Btw, do we have to take care of ABP when TOPOLOGY_SHELLBOLT_MAX_PENDING is
off?
