Hi,
I experienced this strange problem with Emacs 21.3 and 22.0.50
(cvs) under GNU/Linux 2.4.xx or 2.6.xx, glibc 2.3.5. I have no
idea if any other operating systems suffer.
It will be reproduced by the following procedure.
1. Prepare an emacs lisp file.
> % cat foo.el
> (open-network-stream "foo" " *foo*" "localhost" "ssh")
> foo
It seems the fourth arg can be any valid service name.
2. Open a new terminal, or invoke a new shell process by M-x shell.
The shell can be bash, zsh or any.
3. Execute the following command.
> % emacs -batch -q -no-site-file -l ./foo.el
Then Emacs exits before the command finishes, and the following
error message appears.
> SI/O possible
The first "S" is the beginning of error message by Emacs, so
this is "I/O possible".
4. When you repeat the same command in the same shell process,
SIGPOLL will not occur, which seems to be the expected behavior.
> % emacs -batch -q -no-site-file -l ./foo.el
> Symbol's value as variable is void: foo
I hope the problem will be fixed.
