jest reports that cacheable-lookup is leaking

[kirillgroshkov]

This is not my best issue report, since ATM I don't have time to put up the proper minimal repro.

But, when running jest --detectLeaks --detectOpenHandles (I guess only --detectOpenHandles is relevant here) it often prints this:

Test Suites: 1 failed, 11 passed, 12 total
Tests:       1 todo, 17 passed, 18 total
Snapshots:   0 total
Time:        10.615s

Jest has detected the following 1 open handle potentially keeping Jest from exiting:

  ●  DNSCHANNEL

    > 1 | import got from 'got'
        | ^
      2 | 
      3 | const detectLeaks = process.argv.some(a => a.includes('detectLeaks'))
      4 | 

      at new CacheableLookup (node_modules/cacheable-lookup/source/index.js:62:14)
      at Object.<anonymous> (node_modules/got/dist/source/index.js:60:19)
      at Object.<anonymous> (src/jestOffline.util.test.ts:1:1)

I'll just leave this issue there until I have more information, or someone else comes with a better reproduction..

got@11 is used here

Duplicate of sindresorhus/got#1196

const got = require('got');

/*test('test',*/ (async () => {
  const data = await got('https://www.google.com');

//  expect(typeof data).toBe('object');
//  data.destroy(); // The same problem occurs without this code.
})();

If you run this code you can clearly see that the process exits. So it's not Got's neither CacheableLookup's fault. @CatsMiaow already made a comment on Jest repo with simplest reproducible code.
