            Bug ID: 184106
           Summary: Prevent potential uninitialized mach ports returned by
                    mach_port_request_notification
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Misc.
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: bfulgham at webkit.org

If mach_port_request_notification returns an error, the returned previous notification port may be uninitialized. We need to make sure we check error codes returned by this call, and make sure the returned port is always used safely.
