A linux-specific solution could be implemented in terms of cgroups 
<http://www.mjmwired.net/kernel/Documentation/cgroups.txt>. I can’t see any 
way to automatically ensure all descendants are killed, but the parent can 
at least scan the cgroup when the immediate child exits, and kill every 
leftover process it finds.
