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.
