The description is in the individual patches. I had an 00 originally,
but since it was redundant and hard to keep uptodate I dropped it.
My hope is that people will focus more on the code than

We tested quite a lot of applications for a long time.
Most of the tests were with older glibcs using LD_LIBRARY_PATH
before the ld.so interface broke, but there was some retesting
I expect other people will test their applications with it.
There will be some more testing in Intel over time.

A lot of companies should have test systems by now.
A software emulator is available:
[but I don't know currently how to run the test suite with it]
I cannot promise that I'm personally able to test everyone's suggestion.
There are also limitations on sharing performance numbers currently.
