ten second pause at end of typeorm script... why?

index.ts

import "reflect-metadata";
import {createConnection} from "typeorm";
import {User} from "./entity/User";

process.on('exit', () => {
  console.log('exit: ', new Date())
})

createConnection().then(async connection => {

    console.log("Inserting a new user into the database...");
    const user = new User();
    user.firstName = "Timber";
    user.lastName = "Saw";
    user.age = 25;
    await connection.manager.save(user);
    console.log("Saved a new user with id: " + user.id);

    console.log("Loading users from the database...");
    const users = await connection.manager.find(User);
    console.log("Loaded users: ", users);

    console.log("Here you can setup and run express/koa/any other framework.");
    console.log(new Date())

}).catch(error => console.log(error));

output

➤ npm start

Inserting a new user into the database...
Saved a new user with id: 7
Loading users from the database...
Loaded users:  [
  User { id: 1, firstName: 'Timber', lastName: 'Saw', age: 25 },
  User { id: 2, firstName: 'Timber', lastName: 'Saw', age: 25 },
  User { id: 3, firstName: 'Timber', lastName: 'Saw', age: 25 },
  User { id: 4, firstName: 'Timber', lastName: 'Saw', age: 25 },
  User { id: 5, firstName: 'Timber', lastName: 'Saw', age: 25 },
  User { id: 6, firstName: 'Timber', lastName: 'Saw', age: 25 },
  User { id: 7, firstName: 'Timber', lastName: 'Saw', age: 25 }
]
Here you can setup and run express/koa/any other framework.
