Okay so I did that and it does pop up SLDB. But another problem seems
to have to do with the standard streams--stuff I print from other
threads shows up in *inferior-lisp* but nowhere else, that I know of.
I guess by default I'd expect it to come out in the REPL window.
Though it'd be nice to have a way to give a thread its own buffer for
*standard-output*, *standard-input*, *query-io*, etc.
