Hi Aki, thanks again,
I'm just slightly concerned that may be we are seeing a real bug affecting the runs.
There are probably hundreds of WebClient calls in other tests there and only these two hang. So it does not seem to be a test issue.

I'm starting thinking of the following:
- http-hc conduit is affecting it - and it can be causing the problems for two reasons, it has a bug of its own or may be because the tests or WebClient fail to release the resources properly
- or there is some bug in the way new Client API is implemented.

So the next step is to check if it is http-hc which causes it, I've temporarily removed its dependency, can you please, when you get a chance, update the source and run without http-hc ?
I will then continue narrowing down depending on what you see.

In meantime I've added an optional timeout as per your recommendation (except that is optional for now :-)), so it will let users who run builds and see the hangs get the tests running. I guess that in itself should resolve the actual issue, but may be we can trace somehow the actual cause of the problem :-)  
 
Thanks, Sergey
