/*
 * 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.
