Well, on unix the *common-lisp* buffer is definitively "different".
But, even if you run in another thread, the :wait t will block the
entire Lisp. Therefore the timeout will not work. As I said in the previous
email, I believe that the only way is to implement your own waiting loop.
Also, the timeout action could be to sigkill the process, so, you need
access to the pid of the process.
