If you want to deliver a 500 HTTP status code, put 500 to the
HUNCHENTOOT:*APPROVED-RETURN-CODES* list in order to prevent
Hunchentoot's error handling mechanism intercept and mess with the
response.  Edi and I discussed that topic yesterday and we think that
there are some improvements to be made in how Hunchentoot handles
errors.  Expect changes in that area.
