In _cairo_xlib_display_destroy (src/cairo-xlib.c) the
cairo_surfaces:
display->white
display->alpha[0:255]
display->solid[0:16]
are not destroyed. And in _cairo_xlib_surface_put_shm and
_cairo_xlib_surface_update_shm (src/cairo-xlib-surface-shm.c)
'rects' is not freed when rects != stack_rects.</pre>
