Thanks, that was affecting several machines.
Andy, any chance we can do an across-all-machines run of that one on top
of -mm1? Thanks,

Yep, I've run this with badari's fix as a set across the whole family.
I did all dbenchall runs for now as this example is showing on that and
badari's is triggered same. If there is any measure of success there
I'll throw in the externals too.
