I agree that this is a very serious problem.  Setting non-blocking
mode is a radical change to expected semantics, so that if that mode 
is not available, it cannot be right just to leave it off.  

I think the real error is in setting non-blocking mode: that cannot be 
the right solution to whatever problem it meant to solve.  I don't know 
what problem it was meant to solve.  I do know that we have had iostream 
implementations for more than a decade that perform well on both files 
and ttys and do not depend on setting a non-blocking mode.
