> 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.
