I obviously didn't read Andreas's proposal closely enough.  With more  
than a glance, it is clear that a lower-priority helper process is  
used only for a moment to start up the real process at the priority  
requested by the user.

The only problem that I can see with the proposal is that under "heavy  
load", there may always be a runnable process of higher priority so  
that the helper process is starved.  Would this be a problem for  
anyone in practice?  You could always work around it this with:

desiredPriority := Processor activePriority.
[worker := [self runWorkerProcess] forkAt: desiredPriority] forkAt:  
desiredPriority+1
