By bumping the time stamp of _any_ window 'display-buffer' uses for
displaying a buffer (just like XEmacs does).

Then when you switch from one frame to another, any problems you've
found on the previous frame will immediately reemerge on the new frame.

Please put some silly function on 'window-size-change-functions' and
make it produce a backtrace.
