I don't believe I changed anything like this in my commit today, and I
see identical behavior between a 2004-11-06 and 2004-11-07 checkout.
Here is what I think is happening:

The first time you run M-x slime, it makes the *inferior-lisp* buffer
with the pwd of the directory of the current buffer.  So if you were to
try your experiment above and make sure you're in the right directory
before *inferior-lisp* is created, it will work.

However, *inferior-lisp* isn't normally deleted when the Slime
connection is closed.  Afterwards, M-x slime will reuse the same
*inferior-lisp* with the same old directory.

This can be confirmed by playing around with running:
  C-u M-x slime RET pwd RET

The obvious workaround to your problem is to make sure to kill the
*inferior-lisp* buffer before starting Slime.

Hope that helps,
