It worked fine under fairly simple processes, but trying to run things like KDE and Mozilla made it blow up fairly quickly. I suspect that it has something to do with thread upcalls, but I never got around to figuring it out. If someone wants to pick it up, that would be great. Note that this only matters for i386; amd64 has always had its own version of sysenter that it uses. Scott
