While that qualifies as guidance, I'm not sure you've heard me.  Extra 
parallelism is unwelcome by definition in this case.

Also, don't forget that although the parallelism is (sadly only) governed by 
the number of jobs, each job uses resources other than CPU time that the 
developer might be concerned about.
