MAX_POOL_SIZE was hardcoded to 0xFFFFFF00. MAX_POOL_SIZE was replaced with MAX_ADDRESS and POOL_OVERHEAD. MAX_POOL_SIZE is used to prevent a large allocation from passing since adding the POOL_OVERHAD to the allocation (done internally) could cause the size to wrap around and be small. This would cause a return value of success that was an error.
