This is an "untold" story in UNIX which had a major effect on the current environment of UNIX-like operating systems such as the BSD's, Minux and Linux. I wonder where we would be today without the seminal work of people like John Lions who took the time to go through the UNIX System 6 source code and document what each piece of the puzzle did, so it could be taught to those of us interested in learning more about the workings of the system. The paper John wrote went viral and even was published as a book. Force to remove it from publication in 1979 it returned finally in 1996 and is still available today. "You are not expected to understand this" became the hallmark quote of this early work.
