Description:
Our QUEUE implementation should be replaced by a templatized C++ version.
Templatized heaps are
 - type safe
 - easier to read/maintain
 - faster

How to repeat:
Read the code.

Suggested fix:
See http://clustra.no.oracle.com/orabugs/bug.php?id=19844782

Fixed in 5.7.6. Code cleanup. No changelog entry needed.
