Yes, this would be a very useful feature.
We have a couple of tickets in 2.0.10 that will help log statements better, so I'm tentatively adding this one as well.

The logger should emphasize queries that timed out. Clients needs to pay special attention to them as they mark the node down. See RequestHandler#onTimeout.

The unit and integration test cases for this were very comprehensive. I added a few more and did some manual validation with a load test. Looks good to merge!
