Research direction

Start in TestBasicOperation.java at getStreamLargeBatch and the test overloads around lines 270-333, then inspect Producer.close around line 514 and the allocator leak reported by the stack trace. Reproduce the test on Windows CI; done means getStreamLargeBatch is no longer flaky and the allocator closes without reporting leaked memory.
