Thanks Mike. The comment on the private fields in this code use // so I
just kept it consistent.
I didn't get comment about x = unused. The test if unused != 0 was just
to avoid storing to that field as it's a static. Performance wise of
course it doesn't matter what we do as touching each page will typically
result in lots of faulting and I/O.
