How about we keep pending as CONDITIONALLY MANDATORY, but state the 
condition:  The pending state shall be implemented if jobs may not be able
to be proessed for human noticable amount of time, such as a second or more,
in certain circumstances.


How about if the Job Monitoring spec states the condition:


on all CONDITIONALLY MANDATORY attributes?


On all CONDITIONALLY MANDATORY enum values?
