Query: Deadlocked in CONFUSION

Gary Nutt's book is the most confusing approach to Operating Systems I have ever encountered. His constant and confusing mathematical definitions make the simplest topics so confusing, that Einstein or Dijkstra would throw in the towel before understanding them. I am a third year Computer Science student and I have never used a textbook this horrible. If you are a professor, PLEASE consider another textbook for your students! (That is if you want them to learn something other then how to waste money on horrible unedited textbooks)
