           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW

Actual result:
lldb fails to attach to WebContent process with the following error:

attach failed (Not allowed to attach to process.  Look in the console messages (Console.app), near the debugserver entries, when the attach failed.  The subsystem that denied the attach permission will likely have logged an informative message about why it was denied.)
