Actually, I'm not.  IIUC this message appears if a call-process is
interrupted before the subprocess dies.   I think this message in not
desired in general.  It's OK to emit such a message if call-process ends
up waiting a non-negligible amount of time for the subprocess to die
(so as to explain to the user why Emacs is not responding), but for the
usual case where wait_for_termination returns quickly, we should not
emit any message at all.

Patch welcome to fix this problem.

I recently suggested to introduce a message-redirection variable, which
would provide a superset of what you want.  Patch welcome as well.
