> This MBean, implemented as an MXBean, will periodically sample and publish metrics about
the I/O-LOOP thread. e.g.
> * Wait Count:
> *  Wait Time:
> *  Block Count:
> *  Block Time:
> *  CPU time consumed and optional derivatives:
> Additionally:
> * Reset:
> * Last Reset Time:
> I started on this when I realized I was doing something unintended and running my handlers
in the I/O-LOOP thread. I am a JMX wonk so I would be interested in contributing or enhancing
existing JMX services.
> -- Update: I can incorporate https://github.com/rschildmeijer/deft/issues#issue/88 into
this as well, if no one has taken it.
