Yeah, that's no fun. If you're using LOWPORT/HIGHPORT you should 
consider IN_LOWPORT/IN_HIGHPORT.

Trivial jobs aren't really unfair, but if you want to stress the system 
with short jobs you should run the 7.5 series. It has a number of 
optimizations for shorter jobs, including recycling shadows to avoid 
process management overhead.
