enum class Lifecycle

Name	Value	Comments
INITIAL	0	The ThreadDispatcher has been allocated, but not yet associated to a Thread or an aspace.
INITIALIZED	1	The ThreadDispatcher is now associated to its underlying Thread and the containing process's address space, and is waiting to be run.
RUNNING	2	The thread is running.
SUSPENDED	3	The thread is currently suspended. Note that suspension is orthogonal to being "in an exception". A thread may be both suspended and in an exception, and the thread does not "resume" execution until it is resumed from both the suspension and the exception.
DYING	4	The thread is going to die. It may still be interacting with exception handling state.
DEAD	5	The thread is being dissociated from all of its state, and no more interaction with userspace (including exception handlers) is possible.

The only legal transition that isn't from top-to-bottom occurs

when a thread is resumed after being suspended.

enum class Exception

Name	Value	Comments
IDLE	0	There's no pending exception.
UNPROCESSED	1	The thread is waiting for the pending exception to be processed.
TRY_NEXT	2	The exception has been processed, and the next exception handler should be queried.
RESUME	3	The exception has been processed, and the thread should resume.

IDLE threads become UNPROCESSED. UNPROCESSED threads are told

to either RESUME or TRY_NEXT in a loop until they are killed

(no more exception handlers) or resumed, in which case they

become IDLE again.
