=head1 HOW IT WORKS

=head2 is_timeout_call($timeout, callback)
@param Integer $timeout - Set timeout
@param Callback - Sub callback function
@return Boolean
simple: 
            my $start = time();
            my $res = RVL::is_timeout_call(2 ,sub { 
                                for (my $i;$i<99999999999;$i++) {} 
                            });
            if ($res == 1) {
                RVL::print_r("TIME OUT");
                RVL::print_r("Finished after " . (time() - $start). " millisec \n");
            }
