   Weston pointed me at some code in the Python package that checks if Python is finalizing before attempting to do something that might modify reference counts:
   
   https://github.com/apache/arrow/blob/main/python/pyarrow/src/arrow/python/udf.cc#L52-L58
   
   From the R side, our external pointers have an option to not run the finalizer when the session shuts down ( https://github.com/r-lib/cpp11/blob/main/inst/include/cpp11/external_pointer.hpp#L58 ). We could/should pass `false` here since we aren't using the finalizers to do anything that will have an effect outside the process.
