Automatically?  Emacs is oblivious of ctwm restarts.  All it gets are
unmap, map and configure events.

Not really.  The gap results from the fact that after ctwm restarts the
frame has become "normal" again and ctwm applies the resize hints on it.
If 'frame-resize-pixelwise' is nil, ctwm rounds the height to the next
multiple of the frame's line height (+ the basic size).

But you might be able to enhance the f11 specification I sent you
earlier to first shrink the frame by a few pixels and then toggle the
fullboth status again.  So you would have to hit f11 after each ctwm
restart.
