Based on triage comment and docs for EXPLAIN, I intend to propose a patch which masks the number in the 'rows' column of the EXPLAIN output following "DELETE FROM t1", as this number may vary between test runs. Docs say: <quote> The rows column indicates the number of rows MySQL believes it must examine to execute the query. For InnoDB tables, this number is an estimate, and may not always be exact. </quote> http://dev.mysql.com/doc/refman/5.1/en/using-explain.html
