Hi,
In a multi-threaded gtk app, i get errors like:

  Xlib: unexpected async reply (sequence 0x3170)!


I tried this mutex method to stop non-reentrant gdk things
from being screwed:

void draw(GdkDrawable *drawable, GdkGC *gc, gint32 x, gint32 y, gint size)
{
    static GStaticMutex mutex=G_STATIC_MUTEX_INIT;
....
    g_static_mutex_lock(&mutex);
    gdk_draw_rectangle(drawable,gc,TRUE,x-size/2,y-size/2,size,size);
    g_static_mutex_unlock(&mutex);
}

I didn't use gdk_threads_enter()/leave() because this blocks when
it is called from the 'normal' gtk_main thread.
