Scheduling

A Scheduler aims to maximise CPU usage time.

It maintains two main queues of processes.

Ready queue — Queue of processes ready for execution, and waiting for a processor.
Wait queues — Queues of processes waiting for events. There may be multiple queues, one for each event. i.e. a queue for processes waiting for child termination, a queue for processes waiting for I/O completion, etc...
