Can we have a test please? :)

@cliffc-spirent
updating exponential backoff test for truncation
de80d4a 
fixed an issue where a large number of lost packets
would cause the scaled PTO to rollover/overflow to negative
and then zero

updating a related test that was using a large constant delay
and would run up against the new max pto limit

LGTM. We need the CLA before we can merge this though.

@marten-seemann the current status is that the Chief Architect has met with the General Counsel and there are some more internal forms to fill out before the CEO gets to make final approval. I wish I was kidding.
