My testing revealed some issues with the new archive region free code when I forced string verification failure. I’m working with Tom on the issues.

The free_archive_regions code was intended to handle the failed mmap 
case, and thus the regions would have been empty/unused.  So perhaps not 
surprising this requires a small enhancement.
