Since I constantly have to move between different Lisp impls to test things out, I'm interested in running multiple SLIME at the same time talking to different implementations. Anyway, as a first step toward making this a bit more sane, here's a patch that changes the way SLIME builds itself so each impl gets its own directory for its fasl files. Or is there some other way I should be doing this?
