   I have encountered what I think is the same major memory leak when reading large parquet files with `pyarrow.parquet.read_table()`, no pandas even installed.  `pyarrow.total_allocated_bytes()` reports constant numbers, but the actual memory usage just goes up and up and up.
   
   Whatever the problem is appeared between `pyarrow=17` (which uses the expected amount of memory and doesn't leak) and `pyarrow=18` (which leaks like a sieve).
   
   This is a major regression.
