If you want to apply different limits inside and outside the 
reservation, you'll need to setup different QOSes for inside and outside 
the reservation. One way to do this in a way that is transparent to the 
users is to use the job_submit.lua script to check if the reservation 
has been requested, and set the QOS based on that.
