This was interesting, any chance of making this a separate, free standing boost.component?
If there is interest, we can probably ask a review for it. Given the tight review schedule, it might take a while.
Memory mapped file access have been briefly discussed before and a posix/windows implementation of mem-mapped files by Craig Henderson has been in the sandbox for quite some time.
spirit::file_iterator has different implementations (through a policy), and works on posix/windows, using memory mapped files when available. Plus, there is a freestand version (std::fopen and friends). It uses Boost.IteratorAdaptor (new version).
I'm looking at your spirit::file_iterator impl. Looks pretty cool. One question. Why do failures, such as failure to open mmap posix file, return instead of throw?
