	def run_synchronous(
	self, outputfile: Union[str, Path, None] = None,
	print=print, max_poll_interval=60, connection_retry_interval=30
	) -> BatchJob:
	"""Start the job, wait for it to finish and download result"""

The naming of method BatchJob.run_synchronous is quite confusing:
this is not about running a batch job in synchronous mode (which is not a thing yet, but we've been thinking about doing something like that), but just about starting it and actively waiting.
There is already start_and_wait, which is named more to the point.
