Page allocator moved from pools to IO loops.

The resource pool system is highly hierarchical and keeping spare pages
in pools leads to unnecessarily complex memory management.

Loops have a flat hiearchy, at least for now, and it is therefore much
easier to keep care of pages, especially in cases of excessive virtual memory
fragmentation.
