Description

Tracing is an asynchronous operation, and drivers currently poll to determine when the trace is complete (in a loop with sleeps). Instead, the server could push a notification to the driver when the trace completes.

I'm guessing that most of the work for this will be around pushing notifications to a single connection instead of all connections that have registered listeners for a particular event type.
