This worked for me:
#!/usr/bin/perl -

use strict;
use warnings;
use threads;
use threads::shared;

my $locked :shared;
lock($locked);
print "locked(main)\n ";

my $thr = async( sub { test() } );
print "starting\n";

my $wait = time() + 15;
until ( my $ok = lock($locked) ) {
    last if !cond_timedwait( $locked, $wait );
}
print "result: timeout\n" if defined $wait;
print "done\n";
exit;

sub test {
    print "started. \n";
    lock($locked);
    print "lock(test)\n ";
    sleep 10;
    print "exiting\n";
  { no warnings 'threads'; cond_signal($locked); }
}
