Normally the memory is not given back, but Perl does make a good faith effort to try to give it back if it is convenient. http://www.perlmonks.org/?node_id=746953 has a couple of examples of where it can happen. However this is not an issue in practice very often. _______________________________________________ Boston-pm mailing list [email protected] http://mail.pm.org/mailman/listinfo/boston-pm
