 Yes, kernel no longer crashes and sshd (without fix in PR/38396)
 fails (properly?):
 >> sshd[491]: error: mm_send_fd: sendmsg(7): Invalid argument
 >> sshd[491]: fatal: mm_answer_pty: send fds failed
 >> sshd[491]: error: close(s->ptymaster/0): Bad file descriptor
 >> sshd[554]: error: mm_receive_fd: recvmsg: expected received 1 got 0
 >> sshd[554]: fatal: mm_pty_allocate: receive fds failed
 Should also this be pulled up to netbsd-4?
