Getting a bit tired of this.
Are we supposed to be mind-readers? How else are we to work out why you think Linux needs this feature? What problems it solves? What applications are expected to break and what the breakage patterns are? Why the benefits are worth the maintenance costs and the risk of breakage? Why it's done with a config option and not a boot-time or runtime tunable?
c'mon, you guys have been around long enough to understand this stuff.
