Moving out of the realm of what you can do today, it may be worth adding a key
to the meta file which indicates the tests are not safe for parallel testing.

I prefer this over the inverse (a flag stating that the tests ARE safe for
parallel testing) because moving forward it would be most efficient for large
scale testing if we encourage authors to make their tests safe for parallel
processing.
I agree that this is an important area to look at.

My initial thoughts were also that some indication in the meta file
would be useful. I'm not sure it really matters which way around the
flag is - ideally it would be neutral. The important thing is what to
do when the flag is not present, which would be the normal case
initially.

For safety, in the absence of any other information, the installer would
need to assume that the tests were not safe for parallel testing. If
they wanted to, some smokers could default to testing in parallel and
then send feedback to authors - and perhaps even a patch to the meta
file on success.

But care needs to be taken here. One parallel success doesn't mean the
testsuite is parallel safe in general.
