I observe the same behavior. I tried scrubbing $im as described in "perldoc -q clear" and it still gained memory. I would ask this on the PDL maillist, where the module author frequents. You could also try a different module. Do you really need PDL::IO::GD?

This ImageMagick script seems to hold memory down to runnable levels, although I have not taken it beyond a 20 count. :-) 

#!/usr/bin/perl
use warnings;
use strict;
use Image::Magick;

# largeimage.png is around 180 meg 

my $im = Image::Magick->new; # only make one object

for my $i (0 .. 500)
{
    print "$i\n";
    test();
}


sub test{

 my $path = 'largeimage.png';
 $im->Read($path);
 undef @$im;  #needed if $im is created outside loop

}
