/**
* This is not the set of all possible signals.
*
* It IS, however, the set of all signals that trigger
* an exit on either Linux or BSD systems. Linux is a
* superset of the signal names supported on BSD, and
* the unknown signals just fail to register, so we can
* catch that easily enough.
*
* Windows signals are a different set, since there are
* signals that terminate Windows processes, but don't
* terminate (or don't even exist) on Posix systems.
*
* Don't bother with SIGKILL. It's uncatchable, which
* means that we can't fire any callbacks anyway.
*
* If a user does happen to register a handler on a non-
* fatal signal like SIGWINCH or something, and then
* exit, it'll end up firing `process.emit('exit')`, so
* the handler will be fired anyway.
*
* SIGBUS, SIGFPE, SIGSEGV and SIGILL, when not raised
* artificially, inherently leave the process in a
* state from which it is not safe to try and enter JS
* listeners.
