} Sounds sensible to me, unless someone can dredge up a modern system like

It shouldn't be hard to write a test case though it requires a person to
drive it.  Open /dev/tty, set icanon, sleep while the user enters some
typeahead, set -icanon and then see if you can read the typeahead.  Then
try the icanon flop in the opposite order.  It might even be possible to
do it with a script and stty rather than a C program, although it might
also require that all the frobbing and reading use the same (not a dup of
the same) file descriptor.
