Argh!

Hm, like what do you mean exactly? Do you mean something like

void messagePump(){
    if (osx_gfx_mode == OSX_GFX_WINDOW)
        osx_update_dirty_lines();
     _unix_lock_mutex(osx_event_mutex);
     if (osx_gfx_mode == OSX_GFX_FULL) {
        if ((osx_palette) && (osx_palette_dirty)) {
           CGDisplaySetPalette(kCGDirectMainDisplay, osx_palette);
       osx_palette_dirty = FALSE;
    }
     }
     osx_event_handler();
     _unix_unlock_mutex(osx_event_mutex);
}

then in mzscheme

(while true
   (do-stuff)
   (messagePump))

or something? I suppose this is reasonable but scheme aint the fastest 
thing in the world and then the overhead of calling Allegro might be 
costly, but if this is the only way then I will see what I can do.
