This is the final part of bug 95057. The attached patch adds removal of uploads to evicted resources from the texture upload queue and related tests. Now you can, say, drop the texture budget of backgrounded tabs to 10MB by making the following adjustment: void CCThreadProxy::releaseContentsTexturesOnImplThread() { ASSERT(isImplThread()); m_layerTreeHost->reduceContentsTexturesMemoryOnImplThread( 10*1024*1024, m_layerTreeHostImpl->resourceProvider()); Deciding the exact policy (and what signals to send to what and when) will go into a different bug. For the moment, this just keeps the policy unchanged.

Closing this as WONTFIX because the files for the fix are now under Chromium and not WebKit.
