[NTEmacs] accept-process-output does not return in batch mode

[Tetsuo Tsukamoto]

Hi,

I usually use Emacs under GNU/Linux.  Since someone had told me
that NTEmacs may hang when called noninteractively, I tried to
reproduce the problem under Windows XP/2000.  Reproduced with both
NTEmacs 21.3 (binary got from ftp.gnu.org) and 22.0.50
(i386-mingw-nt5.x.xxxx) of 2005-11-18 which I built with gcc from
cygwin.

I did the following:

1. Invoke a local pop3 server.

% /usr/local/sbin/popper

   (*) Any service may be OK.  I used it since pop3 command is
       simple.  Besides, service does not need to be local.

2. Prepare an emacs lisp file.

% cat foo.el
(setq process (open-network-stream "foo" " *foo*" "localhost" 110))
(process-send-string process "QUIT\r\n")
(accept-process-output process)

3. Call Emacs as the following.

% emacs -batch -q -no-site-file -l foo.el

The prompt never returns until C-c.  If the 3rd line of foo.el is
commented out, the prompt returns immediately.

I have no idea what is wrong, but Meadow 2.10, yet another version
of Emacs under Windows, never causes the problem.  It returns
immediately just like Emacs 22.0.50 under GNU/Linux does.

I'm not even sure NTEmacs does something wrong there, but no doubt
it behaves differently.
