I was the last to work on the patch, and that was about a year or so
ago.  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.
