            Bug ID: 146657
           Summary: [WK2] UIProcess/WebProcess shutdown logic may have
                    race condition
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit2
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: bfulgham at webkit.org

While fixing Bug 146554, I found that I had to update WebProcess::didClose to forcibly stop all media playback.

This was because the standard handling for WebPage::Close was getting missed due to the IPC connection between UIProcess and WebProcess getting terminated before the WebPage::Close message was received.

This should not be needed, and should be investigated.
