But looking at `ps` I see an invocation of haddock that was running for 20 minutes!  This can't be right.

Adding --docs=none apparently didn't work.  I get zillions of failures.

But then it turned out that this failed because I also added -VV, in the hope of seeing what is going on.  So this works

hadrian/build test --docs=none --only=T13199

But this does not (log below)

hadrian/build test --docs=none --only=T13199 -VV

I thought -VV controlled verbosity only!
