Strange you don't get any issues... As X11 is not thread-safe, you should 
get some X11 errors, leading to crashs.

I use python threads, but I have a serializer to push all Qt calls on a 
queue, and this queue is processed from the main thread, using a QTimer 
timeout signal.

But all this is true for Qt3, and things may have changed in Qt4...
