	# of ccache space. There's not much reason to have more than this,
	# because we usually won't need to save cache entries from older
	# builds. Also, there is an overall 10GB cache limit, and each
	# run creates a new cache entry so we want to ensure that we have
	# enough cache space for all the tests to run at once and still
	# fit under the 10 GB limit.
