There's a risk with using mmap: If the file is truncated for some
reason, the mapped pages may no longer be useable, and references to
them may crash the program. (I investigated this a little while I was
working on binutils.) Perhaps that wouldn't happen often, but
deleting autosave files to gain a little bit of space on a nearly-full
file system does happen....
