Description

Currently we can only track the amount of bytes allocated by the main memory pool or the alternative jemalloc implementation. To better understand certain situation, we should provide a MemoryPool proxy implementation that tracks only the amount of memory that was made through its direct calls but delegates the actual allocation to an underlying pool.
