Beautiful!

I just tried this snapshot:

   http://cygwin.com/snapshots/x86_64/cygwin1-20130823.dll.bz2

and my 'ls' test succeeded.

Alas, my Orpie test failed:

   $ PATH=/cygdrive/c/cygwin32/lib/lapack /cygdrive/c/cygwin32/bin/orpie
   Fatal error: exception Assert_failure("main.ml", 30, 3)

Line 30 of main.ml is:

   assert (cbreak ());

So....ncurses isn't working correctly across the exec() boundary?

Oh, it probably will, but a cygcheck dump will tell us when this is 
probably happening, because both Cygwin bins will be in the PATH.

I'm hoping this new behavior will simply serve to let more people move 
to Cygwin 64 before absolutely everything is ported.

To my mind, the biggest negative consequence of this improvement is that 
it might delay the porting of some packages by removing an incentive.
