            Bug ID: 184090
           Summary: Avoid uninitialized mach ports
           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

It is possible for mach_port_allocate to return an error, but we rarely check its return value. The value of the argument passed to mach_port_allocate is not guaranteed to be valid when it returns an error, so there is a potential for us to try to use invalid ports.

We should always check return values, and ensure that the mach port variables we seek to initialize are kept in a valid state.

While we're at it, we should add some additional assertions to confirm we aren't dealing with invalid ports.
