I don't want it to update the ctime either.  I shouldn't have to dump the
file just because someone read it.  It only needs to keep atime from being
changed if you read the file.  If you write to the file, it is still ok
to change ctime and mtime.   I'm looking to preserve the atime so I can still
find unused files (candidates for deletion) even if the hierarchy containing
them has been tar'ed or cpio'ed.  Besides, it's a performance win because
the kernel doesn't have to go back and update all those inodes, sort of like
treating the filesystem as read-only.
