It's not that simple.  The question is why t_refcnt > 1 when there are
no processes left attached to the tty.

I managed to reproduce this as follows:

$ script -q 1 script -q 2 script -q 3 script -q 4 tty

if nothing else is going on at the same time, you should always see the
same output, but instead you see a steadily increasing pts number.
