Fudge. I screwed up the commit message due to a cut-and-paste error
(don't ask - sometimes google chrome and gnome-terminal seem to stop
agreeing about the normal X paste buffer)
And I extra stupidly pushed the thing out after the build succeeded,
not having noticed how I screwed up the trivial commit message.
I've force-updated the public sites, and I really hope nobody pulled
in that (very short) time when my tree had a bogus commit message.
(In case anybody cares, the commit message said "SEQCNT_MUTEX_ZERO"
instead of "Several race fixes in epoll" because that's what I had
looked at in another terminal. So it was a very WTF message)
I think this was only the second time I had a forced push to fix some
stupidity of mine. So it's not exactly _common_, but it's
embarrassing.
