[slime-devel] CLISP on Windows?

So I was under the impression that CLISP and Slime Just Worked on Windows. However I'm trying to build the CLISP lispbox and it's not quite working. As far as I can tell the call to comint-send-string in slime-start-swank-server is not doing much. If I manually call (swank:start-server ...) in the *inferior-lisp* buffer, passing it the name of the file that slime is polling, everything starts up fine. Is there some obvious reason why that might not be working. I'm using the vanilla win32 binaries of CLISP (2.33.2) and Emacs (21.3) supplied by their respective developers and the 1.2.1 tar of SLIME.
