Well, for -current and future 7+, unfortunately, yes. But this only
affecting linux binaries that do the mmap() rather than typical read()
/ write(), which is _hopefully_ rare (err.. not quite, perhaps most
but not all linux games do this).
I will not give up 10 years of wisdom just because of this, hence the
sysctl is disabled by default. Please tell me if I'm wrong (with
proper reasoning, not just "please be like linux") so that this can be
enabled by default.
