channelReader, drop table, rename lock_ table... erstpart man sich das abgleichen...

START TRANSACTION;

 this will block until the last concurrent transaction
   that uses the table is done 
DROP TABLE tab;

ALTER TABLE tab_new RENAME TO tab;

COMMIT;

aus chan_ alles was nicht in lock_ ist, dann chan_ dropen und _lock zu chan_ renamen! **indexes testen -.-
