As Fritz mentioned, I posted a note here -
http://www.pythian.com/blogs/356/oracle-10203-patchset-known-issues-and-bugs

I found the number bug only mentioned in the patch itself:
5705795: MANY CHILD CURSORS CREATED FOR AMAZON-LIKE WORKLOAD IN 10.2.0.3

On ML I found it as Bug 5705795 - Win/Linux: Many child cursors
possible for SQL using BINDS -

Oracle states it is not a bug, but an optimization.  That's something which has 
been around for a long time certainly beofre 10gR2.

Testing has shown that closing the statement without explicitly closing the 
results set does not result in open cursor buildup.  However when the entire 
application is run we still have the problem.   Perhaps there are times when 
one has to close the results set  that the test is missing.
