[slurm-users] job requesting licenses would not be scheduled as expected

[Brian Andrus]

Depending on other variables, it is fine.

The 7 license job cannot run because there are only 5 available, so that 
one has to wait.
Since there are 5 available, the 1 license job can run, so it does.

That is the simple view. Other variables such as job time could affect that.
