I'm aware of these issues.  I never *rely* on volatile, but I use it in
a belt-and-suspenders way.

Also, I think it has a use in conveying the programmer's intent to
human readers.  Whenever I see "volatile", I interpret it as a yellow 
flag that says "Concurrency issues! Slow down and use caution in 
modifying this code!"  I expect other experienced C programmers
to react similarly, and consciously deploy it as a warning.
