 321  * we need this inline - forking from kernel space will result
 322  * in NO COPY ON WRITE (!!!), until an execve is executed. This
 323  * is no problem, but for the stack. This is handled by not letting
 324  * main() use the stack at all after fork(). Thus, no function
 325  * calls - which means inline code for fork too, as otherwise we
 326  * would use the stack upon exit from 'fork()'.
 327  *
 328  * Actually only pause and fork are needed inline, so that there
 329  * won't be any messing with the stack from main(), but we define
 330  * some others too.
