What you mean by "not working"? Does it mean that when you start
a long computation and press ctrl-c the computaion is going
on? On my amd64 when using sbcl when I do:
ss(n) == (s := 0; for i in 1..n repeat s := s + 1; s)
ss(10^9)
and press ctrl-c I get:

Interactive interrupt at #x1005B983D7.
as designed. But this depends on Lisp and operating system.

I plan to look into clef problems, but currently I am busy
with other things. Some people use 'rlwrap' (look in the
old posts for exact intruction how to use it).
