* The signature for the cleanup method.

* Arguments indicate the exit status of the child process.
*
* If a Promise is returned, then the process is not terminated
* until it resolves, and the resolution value is treated as the
* exit status (if a number) or signal exit (if a signal string).
*
* If `undefined` is returned, then no change is made, and the parent
* exits in the same way that the child exited.
*
* If boolean `false` is returned, then the parent's exit is canceled.
*
* If a number is returned, then the parent process exits with the number
* as its exitCode.
*
* If a signal string is returned, then the parent process is killed with
* the same signal that caused the child to exit.
