What version of Bun is running?

1.3.1+89fa0f343

What platform is your computer?

Microsoft Windows NT 10.0.19045.0 x64

What steps can reproduce the bug?

npm i lzma

require("lzma");
console.log("OK");

What is the expected behavior?

Program prints OK and terminates.

What do you see instead?

Program prints OK and then keeps running until Ctrl+C was pressed.

Additional information

I initially reported this in #24438 but I realise I did not narrow down the cause correctly. The lzma library does seem to register a sort of 'worker' which might be related to this. I checked that this behaviour is specific to Bun as it does not repro under Node.
