Description

parse_fns3 driver object and parse_baton can make a circular references through the pool cleanup callback registration which is not visible by Python interpreter.

 

If parse_fn3 driver and parse_baton object are allocated from same pool,  the python wrapper object of the pool and its entity pool can't clean up.
