This was discussed on emacs-devel, and the emacs maintainers prefered
the C level implementation for various reasons.

IMHO this C level patch is fairly simple so it should be possible to
apply it to xemacs also, although I dont know much about xemacs.
Maybe someone more familiar with xemacs would care to comment. 

I think its difficult to implement this particular interface on the lisp
level, but I might be mistaken. The interface being that you bind a
plist to the windows object, with properties that modifies the behaviour
of windows operations.

Currently the interface appears to become very simple, and I would like
to solicit opinions about it:

- A window property that allows you to "pin" the window, or rather
  inhibit delete-other-windows for it. This is currently implemented.

- A window property that allows you to group windows together, such
  that other-window only cycles between windows in the group.

implement much of the current functionality ECB now uses advice for.
