This fixes a regression introduced in Bun v0.1.12 where `fetch()` with a body would fail to write the body when the body was small. This also adds `keepalive: false` and `timeout: false` to `fetch` as options.
Please see [Bun v0.1.12's release notes](https://github.com/oven-sh/bun/releases/tag/bun-v0.1.12), as a lot more changed there.
