Dear Emacs developers,,

I now realize I called

ALTERNATE_EDITOR=/bin/false  ${EMACSCLIENT} --alternate-editor=/bin/false -s 
"${EMACS_SERVER_NAME}" --eval "(+ 1 1)"

from within a frame connected to the very same Emacs
server.  This stalls.  After pressing C-g Emacs hangs
and I can get the provided backtrace.

Obviously that was a user error, but I don't know if
Emacs should be allowed to hang in this way in this
case.

Ciao; Gregor
