Previously, the scoping of the timedOut variable in timeout meant that if any call to wrapped function timed out, any subsequent calls would also give a ETIMEDOUT error. This PR fixes that by moving the variables down one scope, so they are reinitialized each call. As a side benefit, it also lets the wrapped function be passed to functions such as async.forEach.

I noticed this style in ensureAsync. I think I prefer it over the args.concat(namedFunction) style. Should I change it back to the way it was before?

This is fine. args.concat(namedFunction) is nice because it's a singe expression that returns the resulti, but it also creates a new array. push is fine here because nothing else re-uses the args array.

Amazing that this wasn't caught until now. It makes me feel like no one was actually using timeout....
