The original change made intuitive sense, some of the arguments against seem a bit weird - asserting that MMAPing the file could mean the memory sticks around after the program stops.. no. Suggesting that MMAP limits things to the size of the ram, well - no, as well - paging may happen, but then we are just back out to the file. Honestly, some of the weird assertions wouldn't take long for people to double check an verify (or falsify).
