This might be related to the Async Device Stream Interface?

@zeroshade Can you take a look at this?

[zeroshade]

The Async Device Stream tests absolutely rely on threading being enabled due to locks and handling. I assume we have a macro for checking whether threading is enabled so I can disable the test if threading is disabled?

[pitrou]

Yes, there's probably a macro somewhere :-) @kou knows more about it.
