I think that's impossible in general, unless we restrict what Lisp
programs can do. Every programming language can be used to write a
buggy program.
However, it should be possible to prevent some cases of such
problematic behavior, certainly so when the infloop is caused by our
bug. But for that we need to know the details of the specific case in
order to investigate.
