`process-pool` allows you to do CPU expensive stuff in multiple processes to make use of multiple CPU cores.

## Usage

Assume we have a `main.js` and `worker.js` like this:

```js

// main.js

const Pool = require('@gera2ld/process-pool');

(async () => {

  const pool = new Pool(3, `${__dirname}/worker.js`);

  const [result1, result2] = await Promise.all([

    pool.invoke('add', [1, 2]),

    pool.invoke('minus', [4, 3]),

  ]);

  console.log(result1, result2);

  await pool.destroy();

})();

```

```js

// worker.js

const worker = require('@gera2ld/process-pool/lib/worker');

class Handler {

  add(a, b) {

    return a + b;

  }

}

// Set a handler with preset methods

worker.setHandler(new Handler());

// Add other methods

worker.setMethod('minus', (a, b) => a - b);

```
