Here, I'd like to have users be able to specify the max total run  
time for a parallel job before it's ended.

That way we can have users specify a sanity check on runtime for the  
time being, until we establish some other policies.

But I would be very interested in the answers to the other cases you  
pose as well. I assume for the first you want to use a PERIODIC_HOLD  
expression, but the second would be useful as well.
