I too miss Greg acutely.

The error message arose because of bugs blamed on Greg, arising from the
combination of Datakit code and mpx, both of which were responsible for
innumerable kernel crashes. So one day, needing a new error code for
debugging, EGREG was born. I remember Ken being the creator, but it might
have been Dennis. Ken's sense of humor is a better match, though. (Or mine,
but I'm not taking credit without corroboration.)
