----------------------------------------------------------

In Warp, I have implemented the idea of [OperationalContexts|https://github.com/arquillian/arquillian-extension-warp/blob/master/impl/src/main/java/org/jboss/arquillian/warp/impl/client/context/operation/OperationalContexts.java]:

* you can choose what contexts you want to propagate (e.g. what is a lifespan of the callable)
* it reflects the hierarchy (nesting) of contexts
* allows extensions for custom contexts

Additional there is [Contextualizer|https://github.com/arquillian/arquillian-extension-warp/blob/master/impl/src/main/java/org/jboss/arquillian/warp/impl/client/context/operation/Contextualizer.java#L62] that you provide with either OperationalContext or its Retriever and it will make the given instance invocations to activate appropriate contexts.

> Expose a Service to execute Callable's and Runnable's within a Inherited context.
> The general idea is to hide the complexity of reactivating the current Contextual information on the new Thread. 
> ExecutorService needs to be a limited view of the java.utl.concurrent.ExecutorService to avoid 'abuse' like shutdown being called prematurely. 
> The submit\(\*\) methods should probably be enough.
