Description Chris Dumez 2021-01-27 10:27:39 PST 
Move ownership of RingBuffer backing used by RemoteAudioSourceProviderManager::RemoteAudio from the GPUProcess to WebProcess, for jetsam purposes. This moves half a megabyte of memory from the GPUProcess to the WebProcess on https://foobar404.github.io/Wave.js.
