2022-07-11 20:01:59 UTC - Brendan Doyle: Couple quick questions regarding intra-container concurrency:

1. Do we have any plans to add support beyond nodejs? This feature is a pretty big differentiator from other faas providers
2. In the documentation for intra-container concurrency, one of the requirements is the akka http client for the invoker server to communicate with action containers. We don't use the akka client due to a comment in the `ApacheBlockingContainerClient`
for a bug in the akka client where requests can hang.
```/**
 * This HTTP client is used only in the invoker to communicate with the action container.
 * It allows to POST a JSON object and receive JSON object back; that is the
 * content type and the accept headers are both 'application/json.
 * The reason we still use this class for the action container is a mysterious hang
 * in the Akka http client where a future fails to properly timeout and we have not
 * determined why that is.```
3. It's been around for quite awhile, but do we consider this feature production ready?
