Review comment:
       If we are executing somewhere that has access to the `Server` object (like the tests `JettySolrRunner`) then we can check if `server.getRequestLog()` returns null. I haven't figured out how to get access to our server object outside of that though. This is what I get when looking at who has a reference to the Server object and none of those seem particularly approachable.
