> 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.
