Then its equally trivial to build with a dynamic root. Please do so,
and don't wreck the performance of the OS I've used since 1994.

In the orginal thread, there was an agreement that the performance
would be measured BEFORE the default was changed, and the default
would only be changed if there was no measurable performance impact.
I believe sam@ asked for this. As far as I know, performance
measurments were never done. Instead, the switch was thrown just
before the code freeze.

Its pretty hard to use the binary update tools that way.
