Changing the desktop is a significantly different operation than  
changing the layout of all the windows.

When changing desktop, you can map all the windows on the new desktop  
with a higher z-value than any of the windows on the old desktop, then  
unmap all the windows on the old desktop. The darcs version of xmonad  
does exactly this on workspace changes (but not the release version).

That strategy doesn't work when the layout of all the windows changes,  
since a window cannot be mapped at two places (and, potentially,  
sizes!) at once.
