Reminds me of the old days when you could reprogram an IBM 360 to do
just about anything you wanted, and IBM would give you the information
you needed.

People developig the MTS time-sharing system (the one that actually
worked efficiently on the 360/67) even got IBM to implement custom
instructions for OS efficiency.
