Well, the simple workaround would be to write a wrapper function for
cygwin_attach_handle_to_fd; the wrapper would call DuplicateHandle to get a

cygwin_attach_handle_to_fd instead of the original handle; that way, when you
close the fd, the duplicate of the handle is closed, entirely independently of
