It's been a couple of months now and I've been warming to CCL, so much so in fact, that it has replaced SBCL as my `other` CL implementation. If you've never used it, it is an Open Source Common Lisp which runs on a number of platforms, including Windows, Mac OS X and Linux in both 32 and 64 bit modes and supports threading on all 3 of these platforms.
There is however a small issue when running Hunchentoot with CCL on Windows; you will notice when connecting to a CCL+Hunchentoot server that it never responds with any content but hangs indefinitely. This is caused by a bug in the CCL Windows timeout handling which requires a small workaround by the user.
Fortunately the workaround is straightforward; simply start up Hunchentoot with the following extra parameters:
> (hunchentoot:start (make-instance 'hunchentoot:acceptor :port 8080 :read-timeout nil :write-timeout nil))
And you are on your way.
