447 * we need this inline - forking from kernel space will result
448 * in NO COPY ON WRITE (!!!), until an execve is executed. This

450 * main() use the stack at all after fork(). Thus, no function
451 * calls - which means inline code for fork too, as otherwise we
452 * would use the stack upon exit from 'fork()'.
453 *
454 * Actually only pause and fork are needed inline, so that there
455 * won't be any messing with the stack from main(), but we define
456 * some others too.
