Description
### Describe the bug, including details regarding any error messages, version, and platform.
I am encountering an IllegalStateException with the message "Memory was leaked by query" when closing a RootAllocator. This indicates that some memory allocated from the allocator was not released before the allocator was closed.
[error.log](https://github.com/user-attachments/files/20497923/error.log)

Contributor guide
Research direction
Start by running the minimal reproducer in the linked liweiyuan/arrow-interop project and compare its behavior with error.log. Trace which allocation remains when RootAllocator is closed; done means the reproducer no longer reports "Memory was leaked by query" or throws IllegalStateException during allocator shutdown.
