        // we wait for that to complete.  If neither is true, we assume the
        // test is synchronous.
        //
        // A 'failing' test will throw an exception.  This exception may be
        // synchronous (i.e., during `main`) or asynchronous (after `main` in
        // lieu of the callback/future).  The latter exceptions are not
        // directly caught.  Instead, we intercept `window.onerror` to detect
        // them.
        //
        // Note, if the test is marked 'negative' or 'fail', than pass and fail
        // are effectively inverted: only a success is reported.
        //
        // In all cases, we funnel test completion through the `finish` handler
        // below to handle reporting (based on status) and cleanup state.
        //
        // A test can finish in one of several ways:
        // 1. Synchronous without an error.  In this case, `main` returns
        //    null and did not set `async_helper`.  `finish` is invoked
        //    immediately.
        // 2. Synchronous error.  `main` throws an error.  `finish`
        //    is invoked immediately with the error.
        // 3. `Future` without an error.  In this case, the future completes
        //    and asynchronously invokes `finish`.
        // 4. Via `async_helper` without an error.  In this case, the
        //    `async_helper` library triggers `finish` via its callback.
        // 5. Asynchronously with an error.  In this case, `window.onerror`
        //    triggers `finish` with the error.
