This is a bug report for perl from jdhedden@cpan.org,
generated with the help of perlbug 1.40 running under perl 5.22.1.


-----------------------------------------------------------------
[Please describe your issue here]

The attached patch upgrades the 'threads-shared' module to v1.51.

The main purpose of this patch is to sync blead and CPAN in
preparation for the release of Perl 5.24.

The patch does not contain any functional changes, but does
removes some dead code from shared.xs.

The patch contains the following POD update:

    Blessing a shared item after it has been nested in another shared item
does
    not propagate the blessing to the shared reference:

    my $foo = &share({});
    my $bar = &share({});
    $bar->{foo} = $foo;
    bless($foo, 'baz');   # $foo is now of class 'baz',
                            # but $bar->{foo} is unblessed.

    Therefore, you should bless objects before sharing them.

This patch is in response to:
    https://rt.cpan.org/Public/Bug/Display.html?id=113905
