Heh, I've actually never tried to use ilisp-recompile-inits before
launching the listener.  This certainly needs to be fixed.

I get the impression that this worked for you earlier.  I wonder
how that can be, since sbcl.lisp used the-function-if-defined and
friends and they are in cl-ilisp.lisp.

Had I had extra time, I would have rewritten the whole mess.  Note
that find-src.lisp is broken as well.  I probably would have
reorganized things between it and implementation specific modules a
bit.  I would also have replaced the-function-if-defined and
friends with something more usable.  Anyway.  I don't see how
reader conditionalizing would buy anything in this case, it would
just pollute *features*.  In general, I try to avoid reader
conditionalization.  Use of it easily leads to abominations like
mk-defsystem.

The reason I put it in cl-ilisp.lisp was that I thought it might be
useful elsewhere.  This was of course just speculation.  And it
indeed assumes that cl-ilisp.lisp is loaded before the
implementation specific module.

Yeah, I agree this is probably a good thing in any case.
