They refer to the "effective priority", I think. Probably, the reason is that if you nest PI and PP locks then you may end up having the Unbounded Priority Inversion (TM) problem if the locker's "effective priority" (inherited one) is higher than the ceiling. I may be missing and/or misunderstanding something, of course. regards, alexander. ______________________________________________________________________________ Werden Sie kreativ!
