Gosh I did that SOOO long ago (almost a year I guess)
that I really cannot remember..
I think I looked at the fields and decided that since there
weren't any at that time It could probably be in that reagion..

Matt has since been there.. I can't remember what was there before.

1.12 (julian 12-Sep-01): struct mdthread {
1.16 (dillon 27-Mar-02): register_t md_savecrit;
1.12 (julian 12-Sep-01): };
