in thread mysterious threads::shared behaviour

So, that explains it. Thank you. I worked around the XML::Dumper issue with the following code: 
my %tmp_h;
for (keys(%h)) {
    $tmp_h{$_} = {};
    %{$tmp_h{$_}} = %{$h{$_}};
}
pl2xml(\%tmp_h, 'h.xml');
%tmp_h = ();

    Where can I read more about LV scalars?

    Try PerlGuts Illustrated as a starting point. Search down for "SvPVLV" for the explanation for LV scalars, though you'll probably need to go back to the top and read down to understand the information presented under that heading.

    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
