Ah, thanks for clarifying. I now see that I already worked around the 
problem in GNU Emacs but forgot about it afterwards. On platforms 
lacking posix_close, Emacs treats a close error with errno==EINTR as if 
the close had succeeded. Although this leaks a file descriptor on some 
non-Linux systems, the leak is unlikely and is better than closing a 
random victim.
