No, because nowait client frames are not recorded as clients.  There's no 
way around it, it's necessary to use frames.

If it's now also necessary to kill the daemon when you close the last 
Emacs frame with the window manager close button (I did not see this 
requirement in your original post), then it's also necessary to kill the 
daemon when you close the last Emacs frame with C-x 5 0 (delete-frame), 
because it's what Emacs tells you to do when you call emacsclient without 
a file argument.

Here's a combined patch, which implements the two desired behaviors, and 
which I believe handles all cases properly: delete-frame, 
handele-delete-frame, save-buffers-kill-terminal, wait and nowait clients.
