It seems that if you use it for intensive usage, I have a memory leak.\r\n\r\nHere is a python script, where I iterate over some items, and when I called the `exists()` function it seems the RAM keeps growing.\r\n\r\n```python\r\nfrom collections.abc import Iterator\r\nfrom pathlib import Path\r\n\r\n\r\ndef check_file(filename: Path) -\u003e None:\r\n    if filename.exists():\r\n        return\r\n    return\r\n\r\n\r\ndef iterate() -\u003e Iterator[int]:\r\n    yield from range(10_000_000)\r\n\r\n\r\nif __name__ == \"__main__\":\r\n    directory = Path(\"/\")\r\n    for item in iterate():\r\n        filename = directory / str(item)\r\n        check_file(filename)\r\n```\r\n\r\nHere also a screen shot that I have using `memory_profiler` library to illustrate it.\r\n\r\n![clean_memory_leak](https://github.com/user-attachments/assets/070d1398-2575-4b2d-84ef-f85879d2e938)\r\n\r\nI do not know if I am missing something here... Let me know if you need more info to reproduce it. I am using `Python 3.12.3` on `Ubuntu 22.04.4 LTS`.\r\n\r\nThanks\r\n\r\n### CPython versions tested on:\r\n\r\n3.12\r\n\r\n### Operating systems tested on:\r\n\r\nLinux","author":{"url":"https://github.com/RegisGraptin","@type":"Person","name":"RegisGraptin"},"datePublished":"2024-08-09T08:30:25.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":8},"url":"https://github.com/122849/cpython/issues/122849"}
