That made sense during development of the feature since we did synchronization asynchronously and wanted to give some grace time for new Interfaces to be added before initiating a new synchronization. On the PM runtime resume path though we do a synchronous restoration of FrameTime and in this case waiting for 1 second before initiating the first operation is clearly wrong. This patch reduces the initial operation time bringing the synchronous call time down by 990 milliseconds.
