Well, I'm having one of those bad days when I try to change too many moving parts at once, so I'm not exactly sure what is broken, but the combination of hunchentoot 0.12.0 and chunga 0.3.1 and the latest SBCL sources running on MacOS yields blank pages (in Camino) and:
"Safari can’t open the page “http://localhost:4242/%E2%80%9D because the server unexpectedly dropped the connection, which sometimes occurs when the server is busy. You might be able to open the page later."
in Safari.
Time to back off to the previous revs and see if things start working again.
