# is not a major problem.
# This should be using the lockfile command, but that's not available on the
# containerized travis and we can't install it without sudo.
# Is is unclear if this is actually useful. I was seeing behaviour that suggested
# concurrent runs of the installer, but I can't seem to find any evidence of this lock
