Looks really nice! I'm playing around..

I have high hopes. I think it buys us some nice freedom, like the
ability to fire up a repl over a socket.

We should probably use our debugger for *inferior-lisp* too. This
possibly gets tricky on e.g. OpenMCL, when Swank and the listener are
different threads. We'd need to become thread-aware as ELI famously
is. In CMUCL/SBCL, I think we just need to save the right Lisp-side
variables and handle :debug-hook event in the idle-state.

I've been holding off on significant backend-hacking until we clean
that whole area up for now.
