Sure. I agree that comments are not the right place for a lecture about 
Poisson stochastic processes. Only the "1000" parameter as an impact on 
the maximum delay that can be incurred with respect do the target average 
delay, and I think that this information is relevant for a comment.

Yep. Maybe "http://en.wikipedia.org/wiki/Exponential_distribution".
