### 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 -- This is an automated message from the Apache Git Service.
