| // Since logging can be asynchronous, its possible for rogue threads to flood the logging queue. |
| // That is, to issue an abundance of log statements faster than the logging thread can keepup. |
| // Typically such a scenario occurs when log statements are added haphazardly within large loops, |
| // but may also be possible if relatively slow loggers are being used. |
| // |
| // Lumberjack has the ability to cap the queue size at a given number of outstanding log statements. |
| // If a thread attempts to issue a log statement when the queue is already maxed out, |
| // the issuing thread will block until the queue size drops below the max again. |
| // |
| // This Xcode project demonstrates this feature by using a "Slow Logger". |
