// Async logging using global thread pool
// All loggers created here share same global thread pool.
// Each log message is pushed to a queue along with a shared pointer to the
// logger.
// If a logger deleted while having pending messages in the queue, it's actual
// destruction will defer
// until all its messages are processed by the thread pool.
// This is because each message in the queue holds a shared_ptr to the
// originating logger.
