        We always send the output to a file, not to a terminal, so the
        default width (80 columns) is fine for us.

        Overriding this method means that we don't have to care about
        fcntl.ioctl API differences for different Python versions.

        Under Python3, StringIO.fileno() raises UnsupportedOperation instead

        The C{run()} method returns os.WEXITSTATUS(res) without checking
        os.WIFEXITED(res) first, so it can signal that everything is ok,
        even though something causes dpkg not to exit cleanly.

        Save whether dpkg exited cleanly into the C{dpkg_exited}
        attribute. If dpkg exited cleanly the exit code can be used to
        determine whether there were any errors. If dpkg didn't exit
        cleanly it should mean that something went wrong.

        When dpkg reports an error, a SystemError is raised and cleaned
        up in C code. However, it seems like the Apport except hook is
        called before the C code clears the error, generating crash
        reports even though nothing crashed.

        This exception hook doesn't call the Apport hook for
        SystemErrors, but it calls it for all other errors.
