Hi

Linux's exit_group system call is meant to exit a whole group of processes. 
In order to emulate it correctly, I must be able to cause a process to exit
from another process. 

How could this be done correctly? I tried sending SIGKILL to the members
of the program group, but that does not work very well, as it fires an
unwanted SIGCHLD to the parent. 

Calling sys_exit(l, v, retval) within the context of a lwp different than
l does not work. What alternative do I have?
