I cannot reproduce this in the following environments.
- Cygwin DLL 1.5.5 and 1.5.7
- Cygwin/X release-44
- GNU Emacs 21.3 on FreeBSD 4.8 and 21.3 on MacOS X 10.3
- SFU not installed
- invoked by 'ssh -CXf <hostname> emacs'

In my task manager's process list XWin.exe allocates 2 GDI
objects for a frame and the number of open files does not
affect it.  Closing a frame correctly reduces 2 GDI objects.
