Pavel,
That's a good point, but it certainly complicates both the interface
and the semantics of the container. Could this style of circular
buffer be an adaptor, or perhaps a policy adaptor?
It's worth pointing out that std::vector also suffers this kind of
problem: clear() doesn't actually free any memory (at least on the
platforms I've worked with it on) - it's the programmers responsibility
to convince the container to release unused memory.
There was also some related dicussion in June in relation to a
re-allocating circular_buffer. (Howard Hinnant)
