### Describe the bug, including details regarding any error messages,
version, and platform.
Hello,
On both macOS/linux py3.12/3.13 pandas 2.3.0 & 2.3.3, the following script
leaks memory with pyarrow 21.0.0. 20.0.0 is ok.
```python
import os
import psutil
import numpy as np
import pyarrow as pa
n = 10_000_000
tbl = pa.table({"a": np.arange(n)})
proc = psutil.Process(os.getpid())
while True:
tbl.to_pandas()
print(f"{proc.memory_info().rss / 1024**3:.2f} GB")
```
Using `jemalloc` mitigates the issue but does not fix it completely.
