[tbnl-devel] Help needed in handler function with (sleep seconds)

I have defined this function as an handler:

(defun my-handler () (sleep 2) (no-cache) (with-html (:html (:body (:h2 " Wait Test Perfomed") ) ) ) )

and added (create-prefix-dispatcher "/tbnl/test/myhandler.html" my-handler) as a list into *dispatch-table*.

When I access /http://linuxbox/tbnl/test/myhandler/ I cannot see anything but if I comment out (sleep 2) from my-handler everything works fine and the message Wait Test Perfomed is displayed on the browser.

Can you please explain me what is going on ?

My purpose what to test TBNL under long-lasting function handler, like handler accesing database via CLSQL.

Thanks,
