-     * to RM does within a properly guarded critical section that first ensures
-     * it is not in the process of being used within a callback. This means
-     * the callstack must take into consideration that pointers are not in
-     * general unique handles if they may have been freed, since a subsequent
-     * malloc could return the same pointer value at that point. This callchain
-     * avoids that by leveraging the behavior of the underlying RM APIs:
-     *
-     * 1) A callback handle is referenced relative to its corresponding
-     *    (semaphore surface, index, wait_value) tuple here and within RM. It
-     *    is not a valid handle outside of that scope.
-     *
-     * 2) A callback can not be registered against an already-reached value
-     *    for a given semaphore surface index.
-     *
-     * 3) A given callback handle can not be registered twice against the same
-     *    (semaphore surface, index, wait_value) tuple, so unregistration will
-     *    never race with registration at the RM level, and would only race at
-     *    a higher level if used incorrectly. Since this is kernel code, we
-     *    can safely assume there won't be malicious clients purposely misuing
-     *    the API, but the burden is placed on the caller to ensure its usage
-     *    does not lead to races at higher levels.
-     *
-     * These factors considered together ensure any valid registered handle is
-     * either still in the relevant waiter list and refers to the same event/
-     * callback as when it was registered, or has been removed from the list
-     * as part of a critical section that also destroys the list itself and
-     * makes future lookups in that list impossible, and hence eliminates the
