I'm running already the latest darcs version:

[3049 /data/src/xmonad/xmonad.darcs$] darcs log --last 1

  * change the default mod+p binding to keep up with changes to dmenu

The code for replacing and handoff is actually there - that's where i've
taken some of these snippets above.

However, there is no general registration code at startup.
xSetSelectionOwner is only called in line 390 from

replace :: Display -> ScreenNumber -> Window -> IO ()

Am I supposed to start XMonad always using the --replace option?
