Always

Description

After closing a realm connection, I expect that realm kills all processes related to Realm, but instead there's always one process that keeps hanging on Windows. This doesn't seem happen on MacOS, just Windows.

Can you reproduce the bug?

Always

Reproduction Steps

• First thing you need to setup an electron app, which you can use this template for an easy setup.
• Go to release/app and run yarn install realm.
• Create any Realm App with Sync (flexible) enabled.
• Open the realm connection in the main process of Electron.
• Close the realm connection before exiting the app.
• Check task manager for hanging process.

Example code:

...
const app = RealmApp({ id: 'MY_REALM_ID' });

const openRealm = async () => {
    // run realm login

    const realm = await Realm.open({
        schema: [MySchema],
        sync: {
            user: app.currentUser,
            flexible: true,
        }
    });
   realm.close();
}
...

After the above code runs and you close the app, there will be one process from the app still running. If I don't call the function openRealm, all processes are closed.

I also tested without using sync, and for that everything works fine, so I'm guessing it's something related to syncSession. Example:

...
const openLocalRealm = async () => {

    const realm = await Realm.open({
        schema: [MySchema],
    });
   realm.close();
}
...

This code works as expected, no process hangs after app is closed.
