Grading for Question 3 -- 9 points

I was a little lenient here. In general, definitions should be precise, and if I had been nit-picking, I would have taken off more points for precision than I did. For example, the following defintion of thrashing is not really correct: ``Thrashing is where the working set of a process is bigger than physical memory.'' Why is this incorrect? Because a process can thrash simply because its working set is bigger than the amount of memory allocated to it, regardless of the total size of physical memory. But that is a subtle point, and you were under time pressure, so I took imprecise answers.
