It was reported that ')display op groebner' and similar commands
cause sbcl errors instead of giving result (issues 152).
The attached patch at least partially works around the problem: it
catches frequent offender before it can cause trouble. It is
possible to catch more cases, I am not sure if it is worth the
effort.
