	## We want the CI to run on both branches and tags, so we should either have:

	## - or neither of them.
	## But it's important to not have only one or the other.

	# In this file, we set `--cpu-shares 4096` on every job. This might seem useless
	# since it means that every container has the same weight which should be
	# equivalent to doing nothing, but it turns out that OpenJDK computes
	# `Runtime.getRuntime.availableProcessors` by dividing the cpu-shares value if
	# it exists by 1024 (cf
	# http://mail.openjdk.java.net/pipermail/hotspot-dev/2019-January/036087.html),
	# so this means that we effectively run every job with 4 cores. This is much
	# nicer than setting `--cpus 4` because the latter enforces CPU quotas and ends
	# up slowing our jobs more than needed. It's equivalent to running the JVM with
	# `-XX:ActiveProcessorCount=4`, but since our tests can spawn new JVM in many
	# places, it would be very hard to ensure that this option is always passed to
	# `java` (we could use the `_JAVA_OPTIONS` environment variable, but this prints
	# text on stderr and so can break tests which check the output of a program).
