The free threading build uses QSBR to delay the freeing of dictionary keys and list arrays when the objects are accessed by multiple threads in order to allow concurrent reads to proceeed with holding the object lock. The requests are processed in batches to reduce execution overhead, but for large memory blocks this can lead to excess memory usage.

Take into account the size of the memory block when deciding when to process QSBR requests.
