| X11 doesn't have a snarf buffer. Instead it has an idea of which
| window currently "owns" the snarf (X11 would say `selection'), and
| when you want to find the snarf contents you go ask the current owner.
| There is no central buffer like on Plan 9's /dev/snarf or the Windows
| clipboard. (In addition to making things a lot more complicated, this
| means that snarf contents do not persist once their owner exits. But
| that particular problem isn't relevant here.)
No, it really does have a CLIPBOARD property, separate from selections
like PRIMARY. A program like xclipboard or kde's klipper or whatever
the gnome thing is, maintains this.
