CI test output shown twice

[rade]

Take a look at a recent Weave CI test, in particular the output produced by the

$ cd $SRCDIR/test; eval $(./gce.sh hosts); export COVERAGE=true; ./run_all.sh (0)

test step.

It contains the entire output twice. Careful examination shows that it is literally copied, i.e. the tests have in fact only been run once - otherwise reported timing would differ.

The same happens in Scope CI.

I've gone back all the way to our first successful CI run, and the same problem is visible there.

So I do wonder whether this is in fact a recent Circle CI display breakage.
