Sorry, I should have given an reference. This description is copied from
http://www.mcsr.olemiss.edu/cgi-bin/man-cgi?termios. A search for
"PENDIN" and "termios" turns up the man pages for a few different
systems. The linux man page is even more cryptic,

       PENDIN all  characters  in  the  input queue are reprinted
              when the next character  is  read.   (bash  handles
              typeahead this way.)

I've outlined a simple way to solve the problem for the common cases.
I agree it's not 100% satisfactory, but from my experience, I think
you are exagerating the implementation trouble.
