//			The global new and delete are overriden to require
//			a placement argument specify the pool memory comes from.
//			The POOL_TYPE structure is defined in the NTDDK specifying
//			the page.<nl>
//			The user mode version ignores the POOL_TYPE (but must typedef it)
//			and uses the global new and delete.
//
//			The debug version of new uses ExAllocatePoolWithTag (the tag is CICN),
//			the release version uses ExAllocatePool
