static middleware() {
		return _.range(1000).map(() => TestMiddleware);
	}
This page is a smoke test to determine whether or not the amount of middleware in
a page is a performance bottleneck for react-server. It has a middleware chain of
1k copies of TestMiddleware, and the response is returned after this chain.
Note that all that is done within the middleware itself is a small string being appended
to the response. After the response is generated, the page is complete.
