- support TCP sockets for now, i.e. no IPC
- extra features like keep-alive, no-delay etc. are absent due to limitations of uSockets
- fix `jest` to treat `done(nullish)` as success
`Bun.listen()` and `Bun.connect()` would create sockets that under certain conditions with calls to `.end()` or `.stop`, prevents the process from exiting gracefully.
