  1. // This is not the set of all possible signals.
  2. //
  3. // It IS, however, the set of all signals that trigger
  4. // an exit on either Linux or BSD systems. Linux is a
  5. // superset of the signal names supported on BSD, and
  6. // the unknown signals just fail to register, so we can
  7. // catch that easily enough.
  8. //
  9. // Don't bother with SIGKILL. It's uncatchable, which
  10. // means that we can't fire any callbacks anyway.
  11. //
  12. // If a user does happen to register a handler on a non-
  13. // fatal signal like SIGWINCH or something, and then
  14. // exit, it'll end up firing `process.emit('exit')`, so
  15. // the handler will be fired anyway.
  16. //
  17. // SIGBUS, SIGFPE, SIGSEGV and SIGILL, when not raised
  18. // artificially, inherently leave the process in a
  19. // state from which it is not safe to try and enter JS
  20. // listeners.
