Yes although you shouldn't be able to hit this with flow control
enabled. Without flow control we didn't overrun at that level.
it's really a semantics question - do we count stuff dumped
intentionally without flow control as an overrun.
I'm not fundamentally opposed to the idea but it is a change of meaning.
Other views ?
