....scheduling and I O, and use interrupt masking to guarantee integrity of system resources shared across interrupt levels. This approach was efficient in many previous processor architectures (e. g, VAX) where the cost changing interrupt levels was small generally less than ten instructions [Morse et al. 82, Levy Eckhouse 89] In modern architectures, however, interrupt masking may be up to an order of magnitude more expensive, contributing to poorer performance of system code. This research was sponsored in part by The Advanced Research Projects Agency, Information Science and Technology Office, ....
