$image->filehandle('<', ':raw') is opening the file. And it is in your code. So, your code needs to close it.

Not elegant (nor tested), but the following should work:

my $ih = $image->filehandle('<', ':raw');
my $ret = $self->res->set_content_type('image/x-icon')
          ->render_binary($ih);
close $ih;
return $ret;

Update: Rethinking this, the handle created by $image->filehandle and passed to render_binary() is being stored in some object. So, when that object gets destroyed, the handle should be automatically closed.
