Yeah, sorry I pushed a temp commit for the cancellation sample I sent you earlier, to force push over later. Force-pushed now.

Fixes #554
Add tests confirming that
asyncio.Lockandasyncio.Semaphorecan be used in workflow code to control concurrency of coroutines (tasks spawned by the main coroutine, and update handlers).The fact that these tests pass largely follows from the fact that our event loop implementation has functioning implementations of
call_later()call_soon(), so these tests could alternatively be moved into thefeaturesrepo, as part of a feature test confirming that all languages have mutex/semaphore primitives that can be used for this sort of workflow concurrency control.
