@tumativ I understand the intention of this JIRA, but to me looks like
adding this.interrupt() in shutdown() should solve those problems.
We may add a dead watch to the cleaner after this, but it doesn't matter,
this this watch cleaner won't be referenced anymore after shutdown, and it will
GCed.
So why not just do this instead of the complexity changes here? Did I miss
anything?---
