 * Log transmit feedback stats for later analysis.
 * 
 * =d 
 * SRLog records the size, timestamp, and other infor for
 * each packet that passed through.  The list of
 * recorded data can be dumped (and cleared) by repeated calls to the
 * read handler 'log'.
 *
 * =h log read-only
 * Print as much of the list of logged packets as possible, clearing 
 * printed packets from the log.
 * =h more read-only
 * Returns how many entries are left to be read.
 * =h reset write-only
 * Clears the log.
