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.
