In CMUCL, the failure looks like this:

(%i1) a;

Maxima encountered a Lisp error:

 :INTERACTIVE-P fell through ECASE expression.
 Wanted one of (:CLOSE :ELEMENT-TYPE :GET-COMMAND :LINE-LENGTH :CHARPOS
:LISTEN
                :CLEAR-INPUT :UNREAD :FILE-LENGTH :FILE-POSITION).

Automatically continuing.
To reenable the Lisp debugger set *debugger-hook* to nil.

That I don't think we have anyway (would be nice though.)  Terminal
would be fine, but it doesn't seem to like something somewhere here
:-/.

Before that point I'll probably stick with the multithread solution,
which does seem to work OK :-).  Won't help on anything but cmucl or
(maybe) sbcl, but I'm content to work with those for a while.
