 I bet this is the same tty bug that got fixed by Ogawa in commit 
 e043e42bdb. -rc5 has that fix. Mikael?

Hm, I had no debugging enabled, but I think a silent hang in

pty_write()
  tty_flip_buffer_push()
flush_to_ldisc()

can cause the receiving side

tty_read()
  n_tty_read()

to wait forever for updates.  I haven't looked closely.  It seems to
be gone with your latest master in any case.
