Spawn the specified program as a "foreground" process, or at least as
close as is possible given node's lack of exec-without-fork.
Cleanup method may be used to modify or ignore the result of the child's
exit code or signal. If cleanup returns undefined (or a Promise that
resolves to undefined), then the parent will exit in the same way that
the child did.
Return boolean false to prevent the parent's exit entirely.
