Hi,
I updated the SBCL backend to use a character stream to match the swank.lisp changes, which fixes a problem reported by Raymond Wiker on comp.lang.lisp. It doesn't look like the OpenMCL backend needs a similar update, but I'm not certain.
For me the symptom of this problem includes totally hanging Emacs. That's no good, I'm looking for the cause.
Cheers, Luke
