/*
* The hashchange event is dispatched asynchronously, so if we want to observe
* it, we have to yield within run_test(), transferring control back to the
* event loop.
*
* When we're expecting our iframe to observe a hashchange event after we poke
* it, we just yield and wait for onIframeHashchange() to call gGen.next() and
* wake us up.
*
* When we're testing to ensure that the iframe doesn't dispatch a hashchange
* event, we try to hook onto the iframe's load event. We call
* enableIframeLoadCallback(), which causes onIframeLoad() to call gGen.next()
* upon the next observed load. After we get our callback, we check that a
* hashchange didn't occur.
*
* We can't always just wait for page load in order to observe that a
* hashchange didn't happen. In these cases, we call longWait() and yield
* until either a hashchange occurs or longWait's callback is scheduled. This
* is something of a hack; it's entirely possible that longWait won't wait long
* enough, and we won't observe what should have been a failure of the test.
* But it shouldn't happen that good code will randomly *fail* this test.
