I have pushed it down to n_tty line discipline code but not within that.
It is on the hit list but I'm working on more pressing stuff first (USB
layer, extracting commonality to start to tackle open etc etc)

I don't think fixing n_tty is now a big job if someone wants to take a
swing at it. The driver write/throttle/etc routines below the n_tty ldisc
layer are now BKL clean so it should just be the internal locking of the
buffers, window and the like to tackle.

Feel free to have a go 8)
