Perl, how to fetch data from urls in parallel?

I need to fetch some data from many web data providers, who do not expose any service, so I have to write something like this, using for example WWW::Mechanize:

use WWW::Mechanize;
@urls = ('http://www.first.data.provider.com', 'http://www.second.data.provider.com', 'http://www.third.data.provider.com');
%results = {};
foreach my $url (@urls) {
 $mech = WWW::Mechanize->new();
 $mech->get($url);
 $mech->form_number(1);
 $mech->set_fields('user' => 'myuser', pass => 'mypass');
 $resp = $mech->submit();
 $results{$url} = parse($resp->content());
}
consume(%results);

Is there some (possibly simple ;-) way to fetch data to a common %results variable, simultaneously, i.e: in parallel, from all the providers?
