How does the scheduler assign priorities?

[Joel Reymont]

How does the scheduler assign priorities then? Is there a particular  
source code file that I should look at? I'm very interested in the  
logic behind it.

So far it looks like a priority-based approach where priorities are  
assigned depending on the number of reductions. How many reductions  
does a process get before it is rescheduled? Is there a way to  
control that?

	Thanks, Joel
