// The frame test helpers coordinate frame loads in a carefully choreographed
// dance. Since the parser is threaded, simply spinning the run loop once is not
// enough to ensure completion of a load. Instead, the following pattern is
// used to ensure that tests see the final state:
// 1. Starts a load.
// 2. Enter the run loop.
// 3. Posted task triggers the load, and starts pumping pending resource
//    requests using runServeAsyncRequestsTask().
// 4. TestWebFrameClient watches for DidStartLoading/DidStopLoading calls,
//    keeping track of how many loads it thinks are in flight.
// 5. While RunServeAsyncRequestsTask() observes TestWebFrameClient to still
//    have loads in progress, it posts itself back to the run loop.
// 6. When RunServeAsyncRequestsTask() notices there are no more loads in
//    progress, it exits the run loop.
// 7. At this point, all parsing, resource loads, and layout should be finished.
