Slime is currently not prepared for such a setup.  Renaming the
buffers will not help, because there are various places where we
access buffers like *slime-repl* or *sldb* by name.  Also, there is
currently no support for parsing the output of multiple TCP
connections at the same time.

You could start the two CMUCL instances manually (or at least the
second) and give their swank servers different port numbers.  Then you
could connect/disconnect to the instance you want to work with.  [You
probably have to modify swank-cmucl.lisp a bit, so that the server
socket gets not closed after the first connection.]

Hmm... sounds complicated.  Mixing Slime with ILisp will probably not
work very well.

Why do you need two CMUCL instances?  Adding nice support for multiple
simultaneous connections, with separate debugger and separate
listener, is probably quite a bit of work.  You could try to replace
the globals variables we have now with buffer local variables (in the
*cl-connection* buffer) or pack all per connection state in a structure
and place this structure in a buffer local variable.
