            Bug ID: 208273
           Summary: MediaResourceLoader objects are leaking on reddit.com
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Media
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: cdumez at apple.com

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.
