So, I did go ahead and implement this in Cygwin by switching console
buffers.  It works great in a cmd window but not at all in a TCMD
<http://jpsoft.com/> window.  I have used jpsoftware products for longer
than I've been working on Cygwin so that's personally a bad bug for me.

I'm trying to file a bug report but I wonder if this will cause a
problem for other console programs if it doesn't work for a popular
commercial product.
