The operative phrase is "yet". Better safe than sorry. I've not read the paper yet, and I am curious on the performance impact. I don't mind trading some performance for better security. Because when exploits are found in the wild, its too late.

The thing is, this can be disabled A) per thread, and B) can't leak from other processes (it's flushed on each context switch).
So really, we want certain processes with software based sandboxing -- e.g. Javascript interpreters-- to turn this off.
