I meant specifically that local %SIG; does not appear to affect the signal handlers, even though it creates a local, empty %SIG, does not appear to be documented.

use warnings;
use strict;

use Data::Dumper;
local $SIG{__WARN__} = sub { warn "outer: $_[0]" };
warn "one\n";
{
    local $SIG{__WARN__} = sub { warn "inner 1: $_[0]" };
    warn "two\n";
    {
        local %SIG;
        warn "three\n";
        print Dumper(\%SIG);
        {
            local $SIG{__WARN__} = sub { warn "inner 2: $_[0]" };
            warn "four\n";
        }
    }
    warn "five\n";
}
warn "six\n";

__END__

outer: one
inner 1: two
inner 1: three
$VAR1 = {};
inner 2: four
five
outer: six

Okay, so the result for "five" isn't correct... looks like there really may be a bug somewhere.
