I believe my arrays will be limited to 10,000 or less.
Normally I wouldn't be concerned because I've never seen a problem with Perl on a Linux box holding ram after the job completes. I don't know if this is to the credit of Linux or Perl or both. But so far once the job completes it looks like all ram is returned.

in thread Does undef free ram?
However since I'll be using a couple of dozen 10,000+ arrays one after the other during the same job I was concerned about memory during the job.
