It definitely annoys me. The argument is you can't usefully run some large N number of programs at the same time anyway and the driver failing to open is a rate limit. The problem is there are things we could usefully do, like this query, without needing to run a kernel as well. The net effect is we don't run tests widely in parallel because they fail if we do, for this and possibly other reasons.
