You definitely seem to be correct. When I run the same SQL statement independently from SQL*PLUS with autotrace enabled, I see only 200 LIOs instead of the huge no. which I see in the trace file.  

Can you please provide a reference to the document which Oracle support pointed?

Let me emphasize it again - we were told by Oracle that LIOs attributed to this statement is somehow wrong - these LIOs are, in fact, from other statements. I didn't understand why it's accounted in that way (and I doubt that support guy knew it either), but coalescing/rebuilding queues' indexes and IOTs helped.

	Whenever I look at v$sqlarea a couple advanced queue related
	statements are always the top statements, however this is
definitely
	some sort of bug because you never see these processes eating
all that
	much CPU and the numbers reported look down right ridiculous.
