I remembered your description, but it's always nice to see exactly
what's being done. Thanks very much for sending this, we'll integrate
it into the LRTBF.

It got obsoleted by the ipipe testing. It's basically the same thing.
What we were testing in the first released testbench was the usage
of the interrupt pipeline in adeos. Now that Philippe has forked it
out to make it more straightforward for people to look at (instead of
thinking they are looking at a true full nanokernel), it was just
the appropriate thing to do to use the I-pipe patch instead. The
mechansim being measured is exactly the same thing.
