Using read and write; there is no memory mapping, and I don't think we want it.
It doesn't work very well when reading from a networked file system, it makes
error handling unnecessarily difficult, and if you're using it for writing, it's
very fiddly when it comes to committing data.

There may be an argument for read-only mapping of small files, demand paging
style, but things fall apart when the working set size gets larger than memory.
