on my laptop, it takes about two minutes to run the test suite the *first* time, with a clean `~/.rustup/` directory. The test suite uses `--preserve`, so that future runs...
(CI test failure. Hmm. I wonder if something is wrong with how I am generated temporary directories?)
Oh; I wonder if the problem is that `cargo-bisect-rustc` is not on the PATH???
Apparently I might need to use some [relatively new](https://github.com/rust-lang/rust/blob/master/RELEASES.md#cargo) functionality...
