Using an exit handler to deallocate a resource corresponds to RAII only
for objects whose lifetime ends precisely at the time the exit handler
is executed. That could only be objects with automatic storage duration
that are free()d inside the exit handler. All other objects have a
lifetime that ends too soon or too late to qualify as RAII. RAII is
often used for objects with lifetimes that could end long before the end
of the entire program.
