This requires a small change in strwrite() and a distinquishable message from
the tty module. (the problem is in VTIME>0 VMIN=0 - the timoute must be invoked
from the requesting code (strwrite()) not the line displine which may not 
even be called) Also note that any new TCXXX style ioctl also needs to
have corresponding code in strioctl (size and direction information has to
be hard coded). However I would not call these `changes to the mechanism'.
