That may be due to heap fragmentation (memory allocated from the heap
can only be returned to the system from the end of the allocated range,
not in the middle of it).

If the pixmaps no longer show up in xrestop, their memory is freed as
far as the X server is concerned, and they were most certainly allocated
by oxygen-gtk / GTK+.
