sub new_window
{
    my ($self) = @_;
    my $ccwd = readlink("/proc/".$self->{child_pid}."/cwd");
    new urxvt::term $self->env, $urxvt::RXVTNAME, -cd => $ccwd;

    $self->{child_pid} = $pid;  # keep for later determining our shells
                                # CWD for relative path names
    ()
}

This extension is great and should be part of the standard urxvt extensions. Using a tiling window manager, I very often need new terminals in the current working directory.
