Are there several processes running in parallel that use different version of the library?

If they are not parallel, instead of exiting after system returns, loop back up and determine the next set of ENV variable settings for the next run via system.

If several parallel sequential runs, just run as many "top level" instances of the top level Perl program as needed.
