Compounds
class	Thread
	The following class defines a "thread control block" -- which represents a single thread of execution. Every thread has: an execution stack for activation records ("stackTop" and "stack") space to save CPU registers while not running ("machineState") a "status" (running/ready/blocked) Some threads also belong to a user address space; threads that only run in the kernel have a NULL address space.

Enumerations
