Node.JS: Tool to see why process is still running?

Question

Is there a way to see what timeouts, intervals or async operations (or endless loops) are still running and are stopping my process from ending?

The module why-is-node-running is exactly the thing you need.

 var log = require('why-is-node-running')
 setTimeout(function () {
   log() // logs out active handles that are keeping node running
 }, 100)

And the output is something like:

There are 4 known handle(s) keeping the process running and 0 unknown
Known handles:
