Hmm, the use of atomic + a local var might avoid that the compiler optimizes away the local var and just uses m_lastUsedBlock again directly, but I am not sure if we should go that way. If one has concurrent accesses to the buffer from different threads, all is lost, as no part of the buffer is really thread save. (e.g. it will still random crash if the buffer is modified in the main thread).
