Considering support run async func in worker thread?

It seems that ThreadWorker can only accept sync function as args at present. What if provide an options.async, when it sets to be true, then exec async function.

example:

'use strict'
const { ThreadWorker } = require('poolifier')

async function yourFunction (data) {
  return new Promise((resolve, reject) => {
    resolve(1)
  })
}

module.exports = new ThreadWorker(yourFunction, { async: true, maxInactiveTime: 60000 })

In my use case, I use vm2 to run user’s custom code(like google app scripts). And the vm2 is not isolated, so I need to run in worker threads. And the script may contains async func.

Here is an example:

const { NodeVM } = require('vm2');
const { ThreadWorker } = require('poolifier')

async function execVM(data) {
  const vm = new NodeVM({
    require: {
      context: 'sandbox',
      external: false,
    },
    sandbox: {...someModules},
  });
  const exec = vm.run(`
    async function someAsyncFunc(args) {
      await requestSomeApi()
      doSomeCpuSensitive()
    }
  
    //... some other functions

    module.exports = {someAsyncFunc}
  `);
  return exec[data.func](data.args)
}

module.exports = new ThreadWorker(execVM, { maxInactiveTime: 60000, async: true })
