This will actually **not** improve performance most of the time and can actually hurt performance a lot. The only case I can think of that can have better performance is manually managing an object pool. This might improve latency or memory usage. All of the advantage can be obtained by improving the GC itself, which is the preferred way. This feature will also be extremely unsafe and can break many assumptions made in the runtime.
