It's only two in tree users (+ systemtap) so shouldn't be a big hazzle.
And they're all tracers so presumably they all pass time stamps. But please
don't add a multitude of new methods to do this.

BTW I've been using something like that since early 2000. It was called
ktrace and was based on a old SGI patch.
