Ah, thanks Maxim.

The poignant comment is:

    PR kern/89528:
    Ouch! I found a comment in tty_pty.c that it doesn't deallocate
    pty's anymore. Not a single destroy_dev() is called by tty_pty.c.
    This means the FreeBSD kernel leaks a lot of cdev's and thus
    ucred's and my patch is working around another bug.
