Why is it necessary to prevent that ?
What is stopping me from mapping utmp (for example) with
MAP_DENYWRITE ?
... nothing, I just tried it, and getty, login &c didn't leave a

OK, this is going to linux-kernel and linux-alert.
I find it quite astonishing that noone thought about denial of service
when they added this feature !
