GDK definitely doesn't store a reference to the pixmap on the
GdkWindow, so you definitely have to unref() eventually if you want
the client-side memory freed.

I don't see any mention of when you can free the pixmap in the Xlib
book or man pages. If the window manager sets the pixmap as background
tile or something on a window, then you can definitely free it; but
who knows when/if that happens.

Owen will know. ;-)
