In order to accommodate the requirements of re-enabling FBC after page-flipping, but to avoid doing so and incurring the cost of a wait for vblank in the middle of a page-flip sequence, we defer the actual enablement by 50ms. If any request to disable FBC arrive within that interval, the enablement is cancelled and we are saved from blocking on the wait.
