With latest CVS head (under X):

I just tried to create 6 windows on a frame (50x132) with 
the sequence:
 C-x 2 C-x 2 C-x 2
 (click mouse in bottom window)
 C-x 2
 (make second window from the top larger by dragging its mode-line downwards)
 C-x 2

I then grabbed the mode-line of the topmost window with the mouse and
dragged downwards.  This makes all the windows smaller - until a
certain point where suddenly all windows are evenly sized over the
entire frame.  

Very surprising (as I recall it, windows used to disappear when they
got too small, but I may be mistaken).

Depending on the sequence in which the windows are split, the "magic"
resizing of the windows seem to affect all or only some of the
windows.  So it is might be related to "parent/child" window
relationships?
