tokio-timer only supports low resolution timer

[doyoubi]

Hi,

Great lib for batching!!

Just a small problem.
The resolution of tokio-timer is too low. The smallest duration is 1 millisecond.
When batching syscall, we need to use a higher resolution timer.

futures-timer fits the needs but it requires changing the type of the Error returned.
Maybe you can consider moving from tokio-timer to futures-timer.

Oh that's an interesting use-case for sure.
If there aren't any downsides, we could make the switch.
Since we are still in 0.x territory (non-stable) it's fine if we change the error type.

Would you mind creating a pull request for that if you find the time? 😊

@yoshuawuyts fyi. Sounds like something that you might find interesting.

[doyoubi]

Sure! It's just a drop-in replacement.

I'm testing to see whether there are some other problems. I will write some feedback here.

This feature has landed now thanks to @doyoubi. Hurray! 🎉
I've cut a new release and updated the docs to reflect our support for high-resolution timers now.
