This is exactly the type of elegant solution that I'm looking for.  
Unfortunately, this behaves exactly the same as trap 0, proc { endwin 
}.  (What is the difference between at_exit and trap 0?)

Fair enough.  I didn't intend to be antagonistic, but rather to answer 
a flip response in kind.  This mailing list is sometimes frustrating 
because of the preponderance of know-it-all types offering solutions 
that (a) imply you know nothing about the Ruby and (b) --here's the 
rub-- don't even work.

Clever, but I must decline to answer your question about "what makes it 
some hard," because its entirely beside the point.  The issue isn't 
whether it's so hard.  I would prefer to use some kind of trap if its 
available.  My question is whether something like this is, in fact, 
available?  If not, then a simple "NO" will do.
