Here's what I did to test it,

    % src/emacs -Q --daemon
    Starting Emacs daemon.
    % emacsclient --eval '(while t)' &
    [1] 2700
    % emacsclient -c --timeout=2
    Waiting for Emacs...
    Server not responding; timed out after 2 seconds
    % emacsclient -c
    Waiting for Emacs...
    Server not responding; use Ctrl+C to break  C-c C-c
