[GitHub] [arrow] lupko opened a new issue, #34731: [Python] FlightStreamReader does not release GIL in to_reader() method

lupko opened a new issue, #34731:
URL: https://github.com/apache/arrow/issues/34731

   ### Describe the bug, including details regarding any error messages, version, and platform.
   
   `FlightStreamReader.to_reader()` does not release GIL as it creates the RecordBatchReader via call to `MakeRecordBatchReader`. 
   
   `MakeRecordBatchReader` waits for first batch of data to arrive before it returns the RBR => interpreter will essentially 'stop' until the data is available.
   
   Workaround: first call `stream.schema` - this waits for the first batch of data while not holding GIL, then follow with `stream.to_reader()`
   
   
   ### Component(s)
   
   FlightRPC, Python
