+     * Happy scenario:
+     *
+     * - Pause is created by calling internalStop().
+     *
+     *   Pause is released normally by invoking release() during the same test.

+     * Failure scenarios:
+     *
+     * - The test fails due to an uncaught exception.
+     *
+     *   In this case, Test.run() will call internalRecover() which empties the clears all
+     *   async pauses and sets the cancelled flag, which means we silently ignore any
+     *   late calls to the resume() callback, as we will have moved on to a different
+     *   test by then, and we don't want to cause an extra "release during a different test"
+     *   errors that the developer isn't really responsible for. This can happen when a test
+     *   correctly schedules a call to release(), but also causes an uncaught error. The
+     *   uncaught error means we will no longer wait for the release (as it might not arrive).
+     *
+     * - Pause is never released, or called an insufficient number of times.
+     *
+     *   Our timeout handler will kill the pause and resume test processing, basically
+     *   like internalRecover(), but for one pause instead of any/all.
+     *
+     *   Here, too, any late calls to resume() will be silently ignored to avoid
+     *   extra errors. We tolerate this since the original test will have already been
+     *   marked as failure.

+     * - Pause is spontaneously released during a different test,
+     *   or when no test is currently running.
+     *
+     *   This is close to impossible because this error only happens if the original test
+     *   succesfully finished first (since other failure scenarios kill pauses and ignore
+     *   late calls). It can happen if a test ended exactly as expected, but has some
+     *   external or shared state continuing to hold a reference to the release callback,
+     *   and either the same test scheduled another call to it in the future, or a later test
+     *   causes it to be called through some shared state.
+     *
+     * - Pause release() is called too often, during the same test.
+     *
