It's more complicated than that.  But the problem has already been 
debugged and fixed in the emacs development trunk:

   http://debbugs.gnu.org/cgi/bugreport.cgi?bug=8855

Unfortunately, the fix won't make it into emacs-24.3.

I'll defer to Marco on this.

My reading of the documentation is that this is to be expected:

$ man emacsclient
[...]
-n, --no-wait
        returns immediately without waiting for you to "finish"
        the buffer in Emacs.

Is the behavior you described specific to Cygwin?

I use "emacsclient -c" and it works fine.  Or you can use  "emacsclient 
-a '' -c" if you're not sure there will always be an emacs server running.
