I agree something isn't working, that's obvious from the results. That
doesn't change the fact that linuxthreads is a gross hack that does
something two system thread libs are supposed to do. Unless porting
linuxthreads to amd64 is REALLY trivial, you would almost certaintly get
more milege in the longterm working with the people on threads@ to find
and fix the problems with our threading libaries or scheduler. Obvious
things to do include building test cases that require minimal mysql
Any statement of the form "X is the one, true Y" is FALSE.
