> When environment expiration is configured, environments are removed from a
> cache map after some amount of time. This cache map may be accessed by
> multiple ExecutableStage transforms in parallel. During environment
> expiration there is a small time window which allows for an environment to
> still being used while another transform removes, dereferences, and closes
> the environment. This is not expected behavior.
