That's a good question. In the implementation of CString on VS2005 and VS2008, I see that the reference count is in-/decremented with interlocked* functions. I think that's enough to make the CoW implementation thread-safe. I.e. if no single CString object is accessed from multiple threads unsynchronized, I don't see how it can fail.
