A modern programming language that makes developers happier.

Wanted to share this, perhaps I'm missing/misunderstanding something:
I was running a Ktor 2.0 `testApplication` test with 100 async calls by a client . However, it started locking up quite quickly  and not even sending the remaining calls to the server.
At first I thought this problem must be in my service. But in the end it even happened if the service did nothing.
I solved it by configuring the CIO engine for the client
```val client = createClient {
                engine { CIO }
                install(WebSockets)
            }```
(the websockets is there because I needed it..)

I was wondering: is this a known thing ? Or is there a different approach that would be  preferred?

This is a bug so I’ve filed it <https://youtrack.jetbrains.com/issue/KTOR-4431>.
