It is, thanks a lot for the hint. But given your first point about direct execution, this in fact makes me want TEST_OUTPUT_DIRECTORY in contrast to `--root=/path/to/tmpfs`: especially in the context of perf tests, I never run all of them together given that it takes such a long time. So I instead either run them directly or via the `./run` script, and in both cases I definitely want to have them in tmpfs given that there's a lot of disk churn if you're using biggish repos.
