You haven't even try hyperz and you say i have an obvious bug, that's
kind of funny, but you would not know why. I try pretty much all of
the thing my patch do in isolation and combination of each other and
the only way i got improvement is with something similar to this
patch. Remove one things and i can find things program that are more
likely to lockup.
