Trying out a new idea: what if we could tell the buildfarm website
that a certain test is currently expected to fail for reasons we can't
fix yet (configuration change needed but owner not responding, or
bugfix from another project needed, etc)? That could cause it to be
displayed in a different shade of green, or grey, or whatever? Other
kinds of failures would still show as red. Perhaps this would be
configured with a file in a git repo that any committer can push to.
