Thanks, I'm going to look into this.
Now the class bootstrapping is rewritten, so no need for such a class redefinition anymore. Please give it a try. (On my SBCL 1.0.10 for Mac OS X 10.4, it fails with a strange "no suitable method for STREAM-ELEMENT-TYPE", which is said to be fixed in a later version.) The change should be in public CVS in an hour. Lispworks and Allegro still run the test suite fine.
