I got to agree with Eric: I don't think the problem specification is 
clear.  Could you show, in a short code example, how the problem 
currently occurs?  Make a couple of jobs and show how one gets 
"starved?"  See SSCCE:

<http://sscce.org/>

If you have limited resources, I don't see how changing the lock system 
will help.  Limited resources mean some jobs might get starved if other 
jobs hog the resources.  I think an example of how the current system is 
working my help us understand better why you think there's room for 
improvement.
