I have a bunch of delays that could eventually be shortened once I'm sure
the sleep process works on all boxes. But unless MacOS X, I have to
support old crappy HW and MacOS X has the advantage of it's threaded
driver model, allowing it to restore a bunch of things simultaneously.

For now, I still have to figure out how to make sleep actually work on
the Core99 machines (still losing RAM content for now).
