Don't fabricate, Alfred. The SMP code firwst existed as patches by Jack Vogel, then of Sun Microsystems, against the October 27 1995 source tree. The current SMP code is dervied from patches (very minor ones) I did to bring Jack's work up to date in 1996, and a lot of work by a lot of other people, starting with Peter. So don't say it's been two years when it's really been five. Thanks, Terry Lambert terry@lambert.org --- Any opinions in this posting are my own and not those of my present or previous employers.
