fixed bug that created empty result files in no-record mode
mysql-test/t/rpl000007.test
    testing non-replication of load data infile when the table is excluded from replication
mysql-test/t/rpl000016.test
    test purge master logs
sql/slave.cc
    fix memory leaks found by  purge master logs test
sql/sql_repl.cc
    fixed race condition and delete before close bug in reset_slave()

Overall comments - coverage testing is a very good thing!
