Well... when you used Gentoo no doubt it was an older kernel and much
work has been done inside the kernel on the memory front and what you
are seeing are some of those improvements. Many of us are now
questioning the long time rule of swap = physical_ram * 2 these days and
I see it hotting up as systems have more and more RAM now and is only
going to increase.
