 - `recover` is [not implemented](https://github.com/tinygo-org/tinygo/issues/891) in TinyGo, and there's no way to prevent the WASM virtual machine from aborting.

     - Make every goroutine exit as soon as possible, otherwise it will block the proxy's worker thread. That is too bad for processing realtime network requests.
     - We strongly recommend that you implement the `OnTick` function for any asynchronous task instead of using Goroutine so we do not block requests.
