487 * we need this inline - forking from kernel space will result
488 * in NO COPY ON WRITE (!!!), until an execve is executed. This
489 * is no problem, but for the stack. This is handled by not letting
490 * main() use the stack at all after fork(). Thus, no function
491 * calls - which means inline code for fork too, as otherwise we
492 * would use the stack upon exit from 'fork()'.
494 * Actually only pause and fork are needed inline, so that there
495 * won't be any messing with the stack from main(), but we define
