WLI's comments on the patch > are: I'll be damned. This is one of the many pieces people never said much about. Looks relatively thorough. I did a few things to keep pmd caching around that look like they got dropped, but I suppose for a standalone mainline port that's the only option. I'm really astounded ppl are going through the trouble of resurrecting all this stuff. I suppose that means it was valuable to someone. -- wli
