Unfortunately, we do alot of mapping in the current kernel assuming that a map is inherited by default. My (hopefully) fix for the snapshot is to by default inherit for mappings that are MAP_FILE on regular files, and not to inherit for MAP_FILE on device mappings. This will be an approximately correct fix. I am working on it, and have found the 1.2 accelx demo. Will be checking it all out tonight. I would really like for those that can test it to try it out before Jordan's snapshot. I would like for us to make "some" progress on a fix. So, in essence, I don't know what I am going to come up with, but I am committed to fix this da*n problem this weekend :-). I will need some help from some of you for testing. It'll be a few hours before I can come up with some coherent code. (My best female friend, talked me into dinner tonight -- and you know how priorities get screwed up :-))... Thanks. John
