Steps to reproduce: 1. Adding logging in MediaResourceLoader constructor / destructor (ideally with a static count) 2. Go to reddit.com and scroll down for a while -> Notice that we keep constructing MediaResourceLoader objects but that they are never destroyed 3. Navigate tab to about:blank (tab keeps using the same process) 4. Send a memory pressure signal: notifyutil -p org.WebKit.lowMemory -> Notice that the MediaResourceLoader still do not get destroyed.
