When CLISP enters the read part of read-eval-print loop, CLISP empties
the input queue to be sure not to get old input. This is why you can
only input one lisp form. This is what makes CLISP interaction with
EMACS through shell/comint/cmulisp so difficult, because there several
Lisp forms are sent to the CLISP process at once.
