Correct. The &*@^@#%$ delayed ARM link was only meant as a reference on
how this is implemented and obviously as a reminder to the ARM folks to
get this finally done...

The main point is not to introduce new users of this failed programming
model and instead make them use the more future proof implementation
right away - which of course might to turn out to be completely wrong
5-10 years from now :)
