-/**
- * A log manager designed specifically to allow collecting ordered log messages
- * in a multi-threaded environment without involving any kind of locking.
- * <p>
- * It is particularly useful in situations when one needs to assert various
- * details about the tested thread state or the locks it hold while also wanting
- * to produce diagnostic log messages.
- * <p>
- * The log manager does not provide any guarantees about the completness of the
- * logs written from different threads - it is up to the caller to make sure
- * {@code toString()} method is called only when all the activity has ceased
- * and the per-thread logs contain all the necessary data.
