process.domain is undefined after using "await" in node10

When I upgrade to node v10.0.0, I found a problem with domain

Here is the code:

let d = require('domain').create();

d.run(async function(){
    console.log(d === process.domain);
    // true
    console.log(1, process.domain);
    // process.domain exists

    let result = await (async() => {
        return new Promise((resolve) => {
            resolve("ok");
        });
    })();

    console.log(result, process.domain, d);
    /**
     * result: ok
     * process.domain: undefined
     * d: no change
     */
});

As shown by the comments, process.domain is undefined after using await. However, If I remove await, the result will be a Promise and process.domain is the same with d.

Just like the problem mentioned at #10724. It happened again at node v10.0.0. Please take a look.

This is almost certainly related to the switch to using async hooks for domains and as a result we're now affected by #20274

Unfortunately, I don't know a good way to resolve. ping @bmeurer I think we'll need to figure out a path forward with PromiseHooks because this is about to break people using domain.

I'm closing this as a duplicate of #20274, so that we don't spread out the conversation over too many places

Thanks for reporting this!
