EXPECTED BEHAVIOR
-----------------------
For the DB version is 11.2.0.4, it should have already included the fix of Bug 14053795 - DIAGENH: LOW RISK WAY TO GET HEAPDUMP DATA ON BUSY SYSTEMS.

On 11.2.0.4, heapdump should hold the shared pool latch multiple times for each 1024 chunks, not one for a long time.
