Ah, I remember those.

That's part 1. Part 2 is "why didn't a graph library test start
failing as well?"

I doubt there's any assigned responsibility. I was watching, but then
I had to travel and lost connectivity. I did expect that Beman was
going to look things over and make sure there were no new regressions
before the release went out. I hypothesize that part of the problem
is that he's not looking at the meta-comm tests, which include
Boost.Python and Spirit and show regressions against the previous
release, rather than just the last test run. I have been worried for
some time that test effectiveness is diluted by having two
reporting/display systems... did it bite us here?
