Update tokio-threadpool example to use tokio-timer 0.2

[carllerche]

This example uses tokio-timer 0.1. This is an old dependency.

The example should be updated to use the latest release of tokio-timer.

I attempted to fix this in here. When I run the example I don't see the interval stream processed. What am I missing with the timer?

Thanks for taking a stab at this.

The issue is that the timer in 0.2 doesn't spawn a background thread by default, so you are responsible for "ticking" the timer handle.

Looking at the file more closely, I don't think it is very useful anymore. I would probably just delete smoke.rs and remove the old timer dep and call it a day.

Thanks 👍

Ok. No problem. I will create a PR.
