Statement-based binary logging does not work in this case, because:
a) two concurrent statements may have their rows intermixed in the
queue, leading to autoincrement replication problems on slave (because
the values generated used for one statement don't depend only on the
value generated for the first row of this statement, so are not
replicable)
b) if first row of the statement has an error the full statement is
not binlogged, while next rows of the statement may be inserted.
c) if first row succeeds, statement is binlogged immediately with a
zero error code (i.e. "no error"), if then second row fails, query
will fail on slave too and slave will stop (wrongly believing that the
master got no error).
So we fallback to non-delayed INSERT.
