Egad.  Whoever thought *this* was a good idea should be taken out
and shot:
   The independent memory size of any child (except a kernel thread) is added to the score:
       /*        * Processes which fork a lot of child processes are likely        * a good choice. We add the vmsize of the childs if they        * have an own mm. This prevents forking servers to flood the        * machine with an endless amount of childs        */

In other words, server daemons are preferentially killed, and the parent
will *always* get zapped in place of its child (since the child cannot
have a higher score).  No wonder we have to turn off OOM kill.
