Patch globals

[kriskowal]

I altered Chronos to patch the global timers since this would permit it to be used as a drop-in performance improvement.

However, in my particular application, Chronos adds a second to a one-second process, whereas my setTimeout patch shaves off 100ms. It might be good to talk about use cases. Mine in particular is exclusively using setTimeout 0.

Am I missing something or should this line be hasOwnProperty.call(obj, k)?

Hey Kris! Thanks for the pull request!

The goals of chronos and the snippet that I saw from you on Twitter the other day are slightly different, but I thought we used similar techniques so I thought you would be interested. As you mention, your goal is to make 0 timeouts and intervals possible. The goal of chronos, on the other hand, is to prevent against "timer congestion" as I discuss in my blog post: http://fitzgeraldnick.com/weblog/40/

One of the trade offs that chronos makes to do this is to push back timers if the browser isn't responsive. So code isn't necessarily more efficient or performant, however it should make the browser seem more responsive to user input. That said, if your application is experienceing delays of a whole second, then you can try setting the minimum interval lower with chronos.minimumInterval(25). If that doesn't help, I think you may have run in to a bug, and I would love to get a smaller example which could reproduce it. Let me know if this helps at all.

Also, see my inline comment above.

Lastly, I think it probably best not to override the globals by default. I will mess with the code so that there is a function something like chronos.patchGlobals().

I pushed my updates to your code to this branch, do you want to pull them in to your fork so they are associated with this pull request?

Basically, just pulled out the patching of the globals to an optional function and added a test for it. Also, I added the obj parameter to the call to hasOwnProperty, since I assume that was a little bug (correct me if I am wrong).
