So it sounds like instead of the solution we just put in, we should
just expose the ability to use Warp's timeout code directly. This
shouldn't be a problem:

* Expose the Timeout module (maybe in its own package, could be useful
to others)
* Add an extra settingsTimeoutManager :: IO Manager. That way you can
create the manager in Mighttpd and then reuse it in Warp.

Would this address the issue?
