Creating a repository object does not clean up after itself

[tdb01r]

This consumes ever increasing amounts of memory:

#!/usr/bin/perl

use EPrints;

while(1)
{
    my $eprints = EPrints->new;

    my $repo = $eprints->repository( 'devel' );

    sleep(5);
}

And shows the following warning:

Subroutine load_config_file redefined at (eval 1171) line 8.
