Duplicate() breaks in CF9 when duplicating a query returned from a multiple-result stored procedure

Please advise on this bug.  It should be considered critical, I believe, as causes some major issues, and breaks applicaitons completely.

Duplicate() breaks in CF9 when duplicating a query returned from a multiple-result stored procedure.  This does not occur in ColdFusion

8.

Example Code:

The behavior of Duplicate and CFTHREAD are broken.
<br><br>

Call a stored procedure that returns multiple result sets.
<br>
<pre>
CREATE PROCEDURE test_proc
AS
BEGIN

SELECT 1 AS col1_a

SELECT 2 AS col1_b

SELECT 3 AS col1_c

END
</pre>
<br>

<cfstoredproc procedure="test_proc" datasource="cns">

<cfprocresult resultset="1" name="r1">
<cfprocresult resultset="2" name="r2">
<cfprocresult resultset="3" name="r3">
</cfstoredproc>

Dump the results, and observe that the values are correct:
<br>
Value Should Be: 1
<cfdump var="#r1#">

Value Should Be: 2
<cfdump var="#r2#">

Value Should Be: 3
<cfdump var="#r3#">

<br><br>
Duplicate each result and then dump again, observing that the values are now incorrect -
they've somehow all become the same as the third result set.  This same thing happens
if we just duplicate the first result set too - it's value after the duplicate() call is
the value of the 3rd result.

<cfset d1 = Duplicate(r1)>
<cfset d2 = Duplicate(r2)>
<cfset d3 = Duplicate(r3)>

<br>

Value Should Be: 1 (but it says 3)
<cfdump var="#d1#">

Value Should Be: 2 (but it says 3)
<cfdump var="#d2#">

Value Should Be: 3 (but it says 3)
<cfdump var="#d3#">

<br><br>

This same thing happens if we call the procedure and then pass its results to CFTHREAD as an attribute - the query gets passed into the thread with the wrong data.  I'm assuming that this is because CFTHREAD duplicates any query objects being passed as an attribute.
