volatile doesn't help when sharing a memory buffer between threads because volatile carries no implication of a read/write memory barrier.
The C++ standards committee has adopted the same view; existing volatile semantics will remain unchanged and there will be separate semantics for communicating between threads. The C standards committee is only now beginning to address these issues, and so (to my knowledge) has not yet formed an opinion. In the meantime, there is POSIX. -- Lawrence Crowl
