We have sent output from latency before, and the ones I have seen I  
think had a max of like 85us. We never ran it for an hour. We can do  
that with both latency -t1 and -t2.

It is probably our app that has problems, but I am trying to  
understand how the interactions work. The highest priority thread in  
our program does nothing but flip a bit and we're seeing that do weird  
things on a logic analyzer.

Nice angry email! :)
