The idle process.

This process never dies and never sleeps. It's also quite lazy, apathic and sometimes even a little antisocial.

Having an idle process costs us some stack space, but simplifies the interrupt-driven preemption logic because there is always a user context to which we can return.

The idle process is not required for cooperative task switching.
