I wonder if what we see when mixing stdout and stderr onto the same device
is
something related to the implementation of the drivers.


FILE * is layered on top of system calls. If the FILE is line buffered, I
think the POSIX intent is to call write() once per line. Otherwise, it
could be calling write() an arbitrary number of times.

I wonder if the line buffer (setbuf) implementation and termios are
interacting to cause this difference between the various OSes.
