"Dump direct loader index keys"
*Cause: Dumps index keys at various points in a direct load based on the
value of this event.
*Comment: This is bit mask, interpreted as follows:
0x01: dump all keys as they are being built (use judiciously,
as this generates a lot of data!)
0x02: dump index keys which cause OER(1), OER(1409), OER(1452)
