* is no problem, but for the stack. This is handled by not letting
|
|
* main() use the stack at all after fork(). Thus, no function
|
|
* calls - which means inline code for fork too, as otherwise we
|
|
* would use the stack upon exit from 'fork()'.

|

* Actually only pause and fork are needed inline, so that there
|
|
