Radoslaw,
10% improvement isn't very impressive from a switch to mmap. What workload did you test with? What I'd really like to see is testing with databases which are 50%, 90% and 200% the size of RAM ... that's where I'd expect the greatest gain from limiting copying.

Guys, can we *please* focus on the patch for now, rather than the formatting, which is fixable with sed?
