Ah, right - let's do the sigexit() hook then. Do I understand correctly
that this way exit_group() would:

1. for all processes in the same thread group, do:
   a) mark thread exit code in emuldata
   b) send it SIGKILL
2. have a emulation-specific hook in sigexit() to reset the exit code to that
   provided in exit_group()
3. don't need any hook in wait() function for parent, since the exit
   would appear as normal process exit from parent POV
 
Sounds fine.
