gdk_pixmap_unref() is the call one uses to indicate that
your program is no longer interested in a pixmap.

But, when your program exits, X will automatically release
any pixmaps that it is using (1). This isn't Windows.
The reason that the X server remains large is that 
generally under Unix, programs will not get smaller,
but simply keep the free memory in reserve for later
use.

(1) Unless the pixmap is set as the background for the
    root window, and other such special cases.
