most secure way to host with lisp?

I don't dare use any of the http server libraries, as I bet all of them have an exploit or two. mod_lisp is crap. It sends query information on a socket to another lisp process, which is lame. I suppose that is useful for load balancing, but it's still lame. I could just use racket, but that also probably has an exploit or two. I think I will review the entirety of tinyscheme and then recompile it into an apache module. What do you think?

That's all nice and good, but my options are reduced once I insist that it has SSL and is well tested. I could use a chicken apache module though.
