Running in debug mode requires monkey patching

[miguelgrinberg]

In #55 I have removed monkey patching. But based on #65 it appears Flask needs monkey patching when it runs the reloader.

I need to investigate how can the reloader be used without monkey patching.

Actually, for me I only needed monkey patching when flask was _not_ running the reloader. When I ran with app.debug=False, all of my HTTP requests just stalled out. This surprised me enough that I thought I'd let you know.

But adding patch_all() fixed it anyway. Thanks!

@lukeyeager are you doing anything out of the ordinary in your routes? There are certain libraries that may require monkey patching to work well with the gevent server.
