While I have never used setjmp/longjmp myself, I have never written a large
interpreter (for example, a full blown LISP) in C.  Writing a LISP interpreter
in SAIL, I found a non-local goto facility very useful to help in error
handling.  My feeling is that setjmp/longjmp have their legitimate uses, be
they ever so few.
