### Brief System Overview

The top-level scripts and utility scripts should be fairly well-documented. Here
is a brief explanation of how they tie together:

1.  `envs/*` are lists of variables made with bash syntax. A user must set a
    `TFCI` env param pointing to a list of `env` files.
2.  `utilities/setup.sh`, initialized by all top-level scripts, reads and sets
    values from those `TFCI` paths.

      for (List<Integer> contents : SAMPLE_INPUTS) {
        C unfiltered = createUnfiltered(contents);
        C filterThenAdd = filter(unfiltered, EVEN);
        unfiltered.add(4);

        List<Integer> target = Lists.newArrayList(contents);
        target.add(4);
        C addThenFilter = filter(createUnfiltered(target), EVEN);

        assertThat(filterThenAdd).containsExactlyElementsIn(addThenFilter);
      }
    }

	t.msg = "hello, world"
	g = t
}

func main() {
	go setup()
	for g == nil {
	}
	print(g.msg)
}
</pre>

<p>
Even if <code>main</code> observes <code>g != nil</code> and exits its loop,
there is no guarantee that it will observe the initialized
value for <code>g.msg</code>.
</p>

<p>
In all these examples, the solution is the same:
use explicit synchronization.

 *  Fix: Don't permit cache iterators to remove entries that are being written.


## Version 4.0.1

 *  Fix: Tolerate null-hostile lists in public API. Lists created with `List.of(...)` don't like it
    when you call `contains(null)` on them!
 *  Fix: Retain binary-compatibility in `okhttp3.internal.HttpHeaders.hasBody()`. Some unscrupulous
