> When we send an error during shutdown of the {{RemoteDriver}}, we don't wait 
> for the error message to be sent. We just send it and then close the RPC 
> channel. For a graceful shutdown, that doesn't seem ideal. We should at least 
> wait a bit for the RPC message to be sent before shutting things down. I ran 
> some tests locally and its pretty easy to hit a situation where the error 
> message doesn't even get sent to the {{SparkClientImpl}}
