+ * StringFifo: A simple FIFO class for passing strings between threads.
+ * Includes a mutex on the load end to allow different threads to
+ * push strings.  Strings are delimited by null characters, both as they
+ * are pushed into the FIFO and as they are stored internally.  Execution
+ * yields for a pushing thread if there is not room or if another thread
+ * is currently pushing data.  Execution blocks for a reading thread until
+ * there is data to read.
