Yeah one thought that went through my head was that since
I now pick the cookes as consecutive numbers (1..N) anyway,
we could do a very simple-minded checksum on recv_completion
notification to check that the sum of all the cookie values
returned is actually N * (N+1)/2 - and flag errors/warnings
if it is not.. 

this would be a test enhancement I could do later.. first let 
me try to avoid having all this complex timer-triggered code.
