26 // Note on logging severity and verbosity level.
27 //
28 // Reserve LOG(INFO) for messages which are always to be put to log and don't
29 // use the INFO severity for the debugging/troubleshooting type of messages.
30 // Some reasoning behind:
31 //
32 // - Library integration would want to disable "noisy" messages coming from
33 // algorithms.
34 //
35 // - It is not possible to disable INFO severity entirely: there is enough
36 // of preparation being done for the message stream. What is even worse
37 // is that such stream preparation causes measurable time spent in spin
38 // lock, ruining multi-threading.
