We can use @Ignore, if we want it to be excluded for all runs. I've
been playing around with a custom annotation, the '@Exclude', that is
essentially the same thing, but adds 'os', 'arch' and 'vm' properties
to it. We could do this with the existing @Ignore and just put an
expression prefix in the text of the annotation.
