After a few attempts it does not work, not because of TIOCSTI but
because of the reading part. In order to get a keypress, I must disable
terminal canonical mode and set VMIN/VTIME. 

But even if I reinject keypress using TIOCSTI, there are problems
because I interfere with programs that expect other behavior from the
terminal. 

Would it make sense to add a knote in wscons for keypresses, so that
they can be readen using kevent?
