Performance is pretty abysmal. Not as bad as upstream Wine, but still pretty
bad. Removing MAP_R improves it a bit more, but not enough. The fact the game
isn't actually streaming (and given the pattern I don't think we can hack in
NOOVERWRITE either) implies that going further down this route is not going to
help.
