State-Changed-Why:
Great, sounds like the mechanism of the deadlock is understood now, so
let's get this pulled up to 9, 10, and 11.

Sounds like ptyfs will avoid this problem for ssh, but without the
patch, revoke -- whether done explicitly by user programs, or in the
kernel when logging out of a non-pty tty -- will still trigger the
deadlock.
