This is fixing a regression in iOS 11. Previously, we would use mediaserverd and apps using WebViews could play audio in the background. In iOS11 however, we do the networking by ourselves instead of using mediaserverd, and we need to keep the NetworkProcess alive as well to maintain feature-parity. Despite the bug title, this is not and is not intended to be specific to MobileSafari.
