Yes. It's from Bill Pittore and Joe Provino from Sun's East Coast division-
they developed it out of the modload stuff they did for RoadRunner (4.0 based
i386- 25Mhz!). Joe Provino, btw, worked with Bruce Cutler at DEC on RSX-11
before Cutler went off to do VMS.

Jeez- this whole thing could turn into another dump technology love fest, so I
won't answer your comments unless you want to chat via private email... :-)
