Thanks for the confirmation.  It looks like I am allowed to migrate the
machines to a 3GB VM, thus circumventing the heap collision with DLL. 
Meanwhile I've looked at some problems that typically happen when loading
emacs-x11 and it turns out that this loads a number of Windows DLL related
to the display drivers and some others related to networking to low
addresses.  The only way I see to get around that is to try to enable ASLR,
so what's the latest on doing that with Cygwin DLL?  As far as I understand
we should then rebase from 0x50000000 down since the range above is used by
ASLR for any DLL that we still need top load to fixed addresses?


Regards,
Achim.
