I think the solution you propose is sound. Do you think that a quick 
mention about avoiding the `BlockingContext` in a comment would help in case 
someone sees this code in the future and is puzzled as to what it does?

https://github.com/apache/spark/pull/15520
  
That makes sense, thanks for explaining. Would installing a custom 
`BlockingContext` on threads that run tasks also work? I'm not very familiar 
with the internals of the Awaitable api so I'm just throwing this out there in 
the hopes you can tell me more :)

I'm not sure I completely understand why you have to use `Awaitable` 
instead of `Await`. Is it to avoid the [`blocking()` call in 
`Await`](https://github.com/scala/scala/blob/v2.12.0-RC1/src/library/scala/concurrent/package.scala#L168)?
