def queue_file_io_task(self, fileobj, data, offset):
self._transfer_coordinator.submit(<EOL>self._io_executor,<EOL>self.get_io_write_task(fileobj, data, offset)<EOL>)<EOL>
Queue IO write for submission to the IO executor.

        This method accepts an IO executor and information about the
        downloaded data, and handles submitting this to the IO executor.

        This method may defer submission to the IO executor if necessary.
