well, I do accept .8 of the blame. For the remaining .2, I have to
say that with a little time travel in forward direction (especially
since we're not doing isochronous spatial travel any more!), you could
have easily seen Pia's presentation at LCA in a week or so :)

Actually, I was planning on pitching the results to you for lwn; if you
find there are some aspects left in the work that you have not covered
yet, and that's interesting for the community, we'd of course be happy
to contribute a short piece. Pia will post a repo link for the analysis
soon.

Thanks, Wolfgang
