They are not, they're Jeff's problem.
I apologize if I ruffled your feathers. But the buildfarm is a shared
resource and it doesn't do to leave it significantly broken over a
weekend, which I feared you might be about to do. Committing stuff
at 4PM on a Friday is perhaps not the best plan if your intention
is to not work weekends.
On a positive note, at least some of the formerly-pink members
seem to be happy now. So as you hoped, we can get more info about
whether there are less-frequent problems.
As for a permanent fix: maybe, instead of printing fractions when
actual nloops > 1, we should print fractions if *potential*
nloops > 1? That is, anytime we're on the inside of a nestloop,
under a Gather, etc. Seems like this'd not be too hard to track
while recursively descending the PlanState tree.
