I was wrong also, off course it is fsync() which tells the OS to pass along the buffered data to the harddisk controller (which on its turn might still buffer the data for as long as it thinks it is necessary) - but I have a good excuse, I confused fflush() with glFlush() (which indeed causes the buffered OpenGL commands to be executed).
