Online index creation on 9.2

On 9.2.0.3, I have experienced a problem with online index creation. When creating indexes on what I suppose most would consider to be large tables
(with nasty, sharp, pointy teeth and a bad disposition), when Oracle is
doing its initial data gathering, sorting, slicing, and dicing in preparation for the actual creation of the index, it appears that "normal" access to the table -- and this includes selects which do not modify data -- becomes severely reduced to the point that the application is no longer usable. When Oracle finishes with its fact finding mission and begins to build the index (as evidence by the appearance of a segment with a number for a name), everything is OK again. We never had this problem with 8.1.7.X.

Is this a new "feature" of 9.2.0.3? Is there some new magic parameter that needs to be set? Are we wearing the wrong grass skirts and/or incorrectly performing our ritual sacrifice ceremonies?
