Good luck.

If my opinion above is correct, you'll be given a really
hard time if you try to undo dynamic root regardless of
the validity of your argument.  If you're not, I'm wrong.

My goal is to explore speed improvements and caching for dynamically-loaded binaries. We will never want to have all binaries statically-loaded, so why should we get so hung up on statically-loaded executables for performance?

I'd also note that some of my ideas are based on mainframe operating systems that I worked on more than twenty years ago. I am not a kernel-level programmer in Unix land, but I was basically that level on a 370 mainframe OS. We used to run hundreds of users on hardware that was much smaller than the cheapest-shit PC that you can buy today. There are plenty of performance-ideas which Unix has not yet explored. But it never will explore them if there's so much hostility to *trying* some alternate ideas, and then *measuring* how they work out.

One of the things I have liked about some of the work that
Matt has done in the past is that he's good at testing and
measuring things, to make sure a change has had the effect
that he expected it to have.  That's the way to keep moving
forward, instead of constant shouting matches where each
side tries to yell louder than the other side.
