Modern Windows OSes allow a lot more of system memory to be

The strange part, is what is leaking pool, and what combination
of drivers does this ? I've never been able to definitely trace
this down. I think I tried running PoolMon once, and didn't manage
to reproduce the problem.

I did manage to identify leaky drivers a few times with poolmon, but
that was back in the days of NT4 and W2K, not needed it for many years.
