This message is printed when Emacs sends two subsequent requests, but
the reply for the first request has not arrived at the time the second
request is send. The message is there to warn the user that the
second request gets probably queued on the Lisp side. The message is
also printed when the Lisp side hits a bug and enters the debugger
(because the first request is not completed).

It is/was caused by the code that prints the arglist. I now removed
the whole thing that used *print-pprint-dispatch*, because it didn't
work at all in CLISP and the result was different in SBCL and
