What's the point creating a promise if you not going to wait for it?

Not sure why you created a promise here just to ignore it without waiting for it to finish.
Could you help me understand the rationale?

This is problematic because if the queue in the event loop is empty, nodejs will exit at the (broken) promise chain without running onShutdown.
Depending on what is being done in onShutdown, this might mean something won't get cleaned up properly.

@midnight-wonderer ... well hmmm I am also irritated ;-) Need to check it but it seems that you are right. Will provide a fix for it ...
