     *
     * The problem is that on MINGW, GNUStep makes all socket streams
     * blocking, which causes problems with the run loop. Calling this
     * method of the run loop forces it to execute all already
     * scheduled items with a time in the past, before any more items
     * are placed on it, which means that the main game update gets a
     * chance to run.
     *
     * This stops the interface freezing - and Oolite appearing to
     * have stopped responding to the OS - when downloading large
     * (>20Mb) OXZ files.
