There are a couple of "gotchas" with subordinate queues that may or may
not be an issue in your environment:

1.  When the subordinate queue is suspended, the job(s) in that queue
are paused on the host, but not killed. That means they are still
holding on to the memory (and other resources) allocated to them. If one
 job that requires a lot of memory suspends another memory-intensive
job, that can lead to out-of-memory issues, or other issues.

2. If there are often a lot of jobs in superior queue, the subordinate
jobs may be suspended indefinitely, causing them to never complete, or
at least not complete in a realistic time frame.
