ttysleep is called in the ovhiwat case.

I tried to patching to return EWOULDBLOCK instead of calling ttysleep.
console still freeze, and the shell running /etc/rc now sticks as
a zombie:
PID PPID STAT TTY   WCHAN COMMAND
215    1 DEs  tty00 -     (sh)

I also note that the tty is tty00 and not console but looking at other 
machines it seems ordinary business.
