 * 
 * ...
 * Once an 'open_index' request is issued, the HandlerSocket plugin opens the
 * specified index and keep it open until the client connection is closed. Each
 * open index is identified by <indexid>. If <indexid> is already open, the old
 * open index is closed. You can open the same combination of <dbname>
 * <tablename> <indexname> multple times, possibly with different <columns>.
 * For efficiency, keep <indexid> small as far as possible.
