it should work when you define two queues with different h_rt limits  
and so limit the slots each user can use in each queue. This might  
lead of course to the situation, that a short running job can start in  
the queue for longer jobs (unless you request the queue explicitly).

Another approach could be to define two projects, which users have to  
specify for short and long running jobs, then you can stay with one  
queue.

In principle two or more limits can be specified:

limit users {*} queues long to slots=10
limit users {*} queues short to slots=54,h_rt=129600

Unless the limit is also requested with -l h_rt=3600 or alike, it  
won't be enforced though. Maybe it would be an RFE to add a new  
condition "where", where "where" is a resource request. Would also  
ease the setup for other resource limits:

limit users {*} resources big_io to jobs=10
limit users {*} to jobs=50
