Define a custom complex (not requestable/consumable) with a default of 
one and attach it with just set to two to these exec hosts. Each job 
will consume one unit, and hence you can only have a total of two jobs 
on the machine (but you can't use 2. below, because the total limit is 2).

Yes, this is the current behavior. I filled already an issue to suspend 
slots instead aof the whole subordinate queue. For now the only 
workaround is to have two low_prioriry queues with one slot each, and 
set the suspend to one and two in the high priority queue for each of 
the low_priority queues.
