75/**
76 * This is not the set of all possible signals.
77 *
78 * It IS, however, the set of all signals that trigger
79 * an exit on either Linux or BSD systems. Linux is a
80 * superset of the signal names supported on BSD, and
81 * the unknown signals just fail to register, so we can
82 * catch that easily enough.
83 *
84 * Windows signals are a different set, since there are
85 * signals that terminate Windows processes, but don't
86 * terminate (or don't even exist) on Posix systems.
87 *
88 * Don't bother with SIGKILL. It's uncatchable, which
89 * means that we can't fire any callbacks anyway.
90 *
91 * If a user does happen to register a handler on a non-
92 * fatal signal like SIGWINCH or something, and then
93 * exit, it'll end up firing `process.emit('exit')`, so
94 * the handler will be fired anyway.
95 *
96 * SIGBUS, SIGFPE, SIGSEGV and SIGILL, when not raised
97 * artificially, inherently leave the process in a
98 * state from which it is not safe to try and enter JS
99 * listeners.
