The call to |interframe_delay_max_moving_.Add()| below depends on |now|
non decreasing in consequtive calls. However, if two threads are
competing for the lock it may happen that current thread calculates |now|
before the other thread, yet it will get the lock later. This will result
in decreasing local time in consecutive calls and trigger a DCHECK.
The same also applies to |timing_frame_info_counter_|.
Bug: none
