ProcessImpl can be removed when VM no longer uses Get/SetPriority to reserve state vectors.

Does SignalsImpl really need to be resident?

InstructionsImpl is resident because it is considered part of the architecture and making it swappable produces too many subtle problems.

CODE [InstructionsImpl, ProcessImpl, SignalsImpl],

GLOBALFRAME [InstructionsImpl, ProcessImpl, SignalsImpl];

CODE [FrameImpl, TrapsImpl],

GLOBALFRAME [FrameImpl, TrapsImpl],

BCD [MesaRuntime];

Don't let TrapsImpl take a start trap, or it will never finish (for the obvious cyclic reasons).
