> 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}}
