It is not required, however GNUstep does need to know that the app is 
multithreaded.  In a single-threaded app, it doesn't bother locking some things 
internally.  The simplest thing to do is start an NSThread that exits 
immediately when your app launches.  This will ensure that anything that needs 
to be in multithreaded mode is.
