Resource reservation for the resource quota piece? We don't use that at 
the moment -- the moe_limit that's currently in place limits each user 
to only be able to have 20 jobs running, which is the behavior that we 
want. The problem we're having is that other jobs, that don't need or 
use these licenses, get stuck in a "qw" state, and reference the 
moe_limit resource quota. If we go in and disable the resource quota, 
then the job gets dispatched to a node and runs without problem.

If we don't use either "-l qname=...." or "-l hostname=...." when we 
submit the job, then it launches without problem.

If we don't specify a parallel environment, but leave the -l requests in 
the job submission, then it launches without a problem.

While I haven't tested each and every resource that could be requested 
when a job is submitted, the jobs only seem to stick in a qw state if we 
try to request either a queue or a host.
