That would explain why I couldn't find any examples on using this ;-)

This is what I did to make it work for me. A better fix would probably be 
around the struct proc definition.  If fact, you had noted "broken" 
probably as a memo to fix something here...

        struct proc *p = curproc ? curproc : &proc0;    /* XXX broken */
