Yeah - I was kinda hoping the mailing list would give me the direction to go
on this one. The other thing that I considered that might make more sense was
instead to implement these so that when over/underflow checking is enabled we
panic when we get a value out of the range of 0 to KTIME_MAX. Would that make
more sense?
