PERFORCE change 155554 for review

[Ed Schouten]

Hello Mayur,

I don't know a lot about our VM subsystem, but I've got a question about
your work. Some time ago I ran a `buildkernel' with lock profiling
enabled and saw the following results (sorted by `wait_total'):

It seems to me that the "vm page queue mutex" is clearly one of the most
contended locks inside the kernel. Is your work also targeted to reduce
this contention?

Happy 2009!
