I don't understand shrink_windows enough to make it less trigger-happy.
 From the code I only understand that a high value of `window-min-height'
is an invitation to shoot silly windows.

This thread started with an example where a window's height was
explicitly set to a value smaller than the top-level value of that
threshold.  How should Emacs deal with that?  How should Emacs deal with
`gnus-window-min-height' or `emerge-one-line-window'?

In another thread people discuss perspectives a la Eclipse.  How should
Emacs handle one- or two-lines windows in such "perspectives" when
changing the window configuration?  Should perspectives avoid one-line
windows?  Should Emacs be allowed to auto-delete them?
