410 * main() use the stack at all after fork(). Thus, no function
411 * calls - which means inline code for fork too, as otherwise we
412 * would use the stack upon exit from 'fork()'.
413 *
414 * Actually only pause and fork are needed inline, so that there
415 * won't be any messing with the stack from main(), but we define
416 * some others too.
