I've successfully used mmap() a few times in the last few years... Luckily for me the use cases I've had weren't really subject to the same problems I've since read about here and elsewhere: 1) I'm always mmap()ing the whole file (and the files are power of 2 sized). 2) The files I'm mapping are stored on file systems I control (and so are never on NFS). 3) In one case, my use of mmap() is limited to read only.
