This is a bandwidth issue. The compressed archive containing the
interrupt latencies of all our test runs is 100MB. I could provide
a URL _privately_ to a handful of individuals, but beyond that
someone's going to have to host it.
Let me know if you want this.
Of course, now that LRTBF is out there, others can generate their
own data sets.
