It should be possible in a resource quota set rule to specify that a filter is
limited to a resource value of N-A, where N is the total number available, and A
is some constant.  For example:

limit users !@reserved to slots=-10

meaning that users not in the @reserved group can use all but 10 of the job
slots, i.e. 10 job slots are always reserved for the group @reserved.
