Got it. Maybe this is why my get_highest_ready function was failing.

Also, how does the insert_ready function work? What are the rules for a
node being in the ready queue?

I am asking this because I need a list of all the nodes in the system,
which are either ready to execute or are currently executing on a
processor. How do I go about obtaining this list?
