Jung-uk Kim is preparing a patch of 20070126 so hopefully we can test and integrate that. We didn't MFC 20051021 due to a memory leak on some systems (bad refcount). That was fixed a few revisions later, but I remember a few 2006 versions having other problems (hanging on boot) and then I ran out of time to review/debug the patches. Hopefully 20070126 is good and we can commit it quickly, then MFC after a month. -- Nate
