// This class is a concrete of AbstractMessageLoggerScribe
// Its purpose exists ONLY if there is a second thread running the workhorse
// scrribe.  In that case, the workhorse will be consuming from a
// SingleConsumerQ, and this class is the one that places the item on said 
// queue.  It does work that used to be the realm of MessageLoggerQ.
