[tbnl-devel] tbnl/mod_lisp memory leak ?

Hey, I am using tbnl 0.9.10 and sbcl 0.9.11. I have some functions which generate HTML content using cl-who etc. I have run then through heavy testing and they work fine in the REPL (no memory leakage). As soon as I am calling them via tbnl/mod_lisp the lisp memory usage jumps tremendously. I ran the ab2 benchmark (100 requests with concurrency 1) and the memory usage went from 50Mb to 300Mb+. It then starts swapping. Is this a known problem or am I doing something terribly wrong ? -- quasi Utopia Unlimited!
