It turns out that writing tests that contain subtests should probably be
limited to table-based tests and tests that share a common setup shared
between tests.
Writing tests with a subtest like this:
```
func TestSomething(t *testing.T) {
t.Run("Subtest", func(t *testing.t) {})
}
```
Has the following disadvantages:
- It can lead to multiple tests failing with `(unknown)` status when
only one of the subtests hang (never exit)
- In Go 1.20rc1, using `t.Setenv` is no longer allowed if the parent
test is parallel
