When a job on a dynamic slot (slot1.1 for example) completes, the
dynamic slot is marked as "available/unclaimed" for a brief window of
time before it is reaped and the resources it consumes are made
available to the primary slot (slot1).
During that time a job can be scheduled on it.... a job with far less
RAM or #CPUS than the slot has reserved.
This results in a large inefficiency in job allocation when the queue
is very busy, and there are lots of mixed jobs... some reserving high
numbers of cpus and others reserving few.
