   8 When you want to fire an event no matter how a process exits:
   9
  10 * reaching the end of execution.
  11 * explicitly having `process.exit(code)` called.
  12 * having `process.kill(pid, sig)` called.
  13 * receiving a fatal signal from outside the process
  14
  15 Use `signal-exit`.
  16
  17 ```js
  18 var onExit = require('signal-exit')
  19
  20 onExit(function (code, signal) {
  21   console.log('process exited!')
  22 })
  23 ```
  24
  25 ## API
  26
  27 `var remove = onExit(function (code, signal) {}, options)`
  28
  29 The return value of the function is a function that will remove the
  30 handler.
  31
  32 Note that the function *only* fires for signals if the signal would
  33 cause the process to exit.  That is, there are no other listeners, and
  34 it is a fatal signal.
  35
  36 ## Options
  37
  38 * `alwaysLast`: Run this handler after any other signal or exit
  39   handlers.  This causes `process.emit` to be monkeypatched.
