suspect such a cure would be worse than the disease. This is such a rare

200 builds a day or more, and I can't recall having seen this before.
Yeah, I don't remember having seen it before either, but on the other
hand I haven't been paying super close attention.
One easy low-tech fix would be for Marc to publish the exact times at
which the mirror syncs run (I think it might be something like 20 past
the hour but I'm not sure), and then we could tell buildfarm owners not
to schedule their CVS pulls to start in that particular five-minute
window, and committers could try to avoid committing many-file patches
right then either.
Yuck. I think if it gets that far we would have discovered a compelling
reason to abandon CVS, as many bystanders have urged us to do. But I think we
can live with an occasional hiccup.
