Because of how package dependencies work, there could be multiple instances
of this package within an application. To avoid each of these packages having
a process.exit hook, we add all of them to the global scope under a unique
symbol. The first instance created will be the manager of all of these global
packages. This allows for a single process.on('exit') hook to be registered.
