> Tests use {{PortAssignment#unique}} for assignment of the ports to bind
> during tests. Currently, this method works by using a monotonically
> increasing counter from a static starting point. Generally, this is
> sufficient to achieve uniqueness within a single JVM process, but it does not
> achieve uniqueness across multiple processes on the same host. This can
> cause tests to get bind errors if there are multiple pre-commit jobs running
> concurrently on the same Jenkins host. This also prevents running tests in
> parallel to improve the speed of pre-commit runs.
