Mine uses atomic windows.  But window-local tab-bars are not really
useful for displaying window configurations anyway (just like
mode-lines are not suited for displaying the battery charge IMHO).

Anyway, the problem with an X-based solution is that we would have to
find a solution for non-X-based systems.  How "much" X-dependency does
x-tabs have?
