Wait... so the OP's premise is completely wrong? Doesn't the body of a module have to complete before dependent modules will execute their bodies?

In other words, if you put

    for (let i = 0; i < 10e8; i++)
        // blah

in the body of a module, wouldn't that block dependent modules for the duration of the loop?

Would top-level await be different?

edit The premise, as I understand it, is that the module itself is treated as the "currently-executing method" for the purpose of the `await`.
