            Bug ID: 178962
           Summary: Leaking WKWebViewConfiguration when running layout
                    tests
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Tools / Tests
          Assignee: webkit-unassigned at lists.webkit.org

When running layout tests, we leak a WKWebViewConfiguration every times we reconfigure between tests.  I believe I've tracked this leak down to line 477 in WKWebView.mm.

Note that the biggest problem with leaking a WKWebViewConfiguration is that a WKWebViewConfiguration holds a strong reference to the ProcessPool.  In effect, this means that leaking a WKWebViewConfiguration will create orphaned processes.
