The INSERT DELAYED should not maintain its own private auto-increment counter, because this is assuming that other threads cannot insert into the table while the INSERT DELAYED thread is inserting, which is a wrong assumption. So the start of processing of a batch of INSERT rows in the INSERT DELAYED thread must be treated as a start of a new statement and cached next_insert_id must be cleared. mysql-test/r/delayed.result: test suite for the bug mysql-test/t/delayed.test: test suite for the bug sql/sql_insert.cc: Reset auto-increment cacheing before processing the next batch of inserts in the handler thread
