It occasionally failed in test_pty, too, with the very same error
message (that /dev/tty isn't a tty).

Couldn't there be a bug in openpty instead? Perhaps it is trying to
allocate the same device again, but fails to do so correctly, and fails
to recognize that it should use a different one instead.

Anyway, if you still think you need an OS 10 account, please let me
know, and I can give you an account to the machine the buildbot
runs on.
