In effect if the operating system knew about the DRAM layout, it could for instance double critical data structures and race the processing. Maybe this would be helpful in the networking areas.

On the other hand this can maybe get fixed in hardware by just copying the page that's being refreshed to the side somewhere, eliminating the whole waiting problem. Last but not least, AFAIK writes to a row already recharge the capacitors so there shouldn't be a need to refresh it. What am I missing?
