* Also, the changes that affect Xinerama are untested, so Jason, if you can check that out. In particular, I believe focusWindow needs to check for visible workspaces, not just the current workspace.
The zipper as used does breaks Xinerama support. I have two monitors; when xmonad starts, the screen accessible with 'w' contains workspace 1, the screen accessible with 'e' contains workspace 2. If I create an xterm, it pops up on workspace 1 as expected. Under pre-zipper code, if I wanted to create an xterm in workspace 2, I would hit mod-e to switch to the workspace on the other screen. When I try this with the zipper code, the contents of screen 'w' disappear. I can create the xterm, but now, if I want to switch back to screen 'w' from screen 'e', the contents of screen 'e' disappear.
