Richard,
TRUNCATE is still processed internally as DELETE FROM ... in 4.1.1. It is in
the TODO to make use of DROP + recreate of the table. A workaround: use DROP
+ CREATE for fast execution.

Looking to the second query I think you're having a cartesian product. For each row

For each master you will have in your dual master setup you will need to

Your cnf file just needs to have log-bin and unique server-id's. Then use the CHANGE

One of the tricky things about finding errors is that the error is often
