    * builder/builder.py
      common/ExecUtils.py
        - Thread jobs on the builder, even though we can only
            do one at a time right now.  It lets the job proceed
            independently of the XMLRPCBuilderServer.
        - Make the BuilderMock object's log function private
        - Make the XMLRPCBuilderServer's log function private
        - To execute mock, we now fork() and execv() the mock process
            so that we can more reliably gather its output
        - Correctly clean up the mock root directory
        - Rename builder.log -> job.log so it can't get confused
            with build.log from mock
