"Unfortunately, objects don’t compose in the presence of concurrency. They hide the wrong kind of things. They hide sharing and mutation. Let me quote the definition of data race: Two or more threads accessing the same piece of memory at the same time, at least one of them writing. In other words: Sharing + Mutation = Data Race. Nothing in the object’s interface informs you about the possibility of sharing and mutation inside the object’s implementation. Each object in isolation may be data-race-free but their composition may inadvertently introduce data races. And you won’t know about it unless you study the details of their implementation down to every single memory access."

Обмен сообщений требует фактически высокоуровневых ячеек памяти, то есть вся совместимость с старым Си ломается.

Хотя можно было-бы сделать чтобы старый Си жил внутри изолированных виртмашин и никакого шаринга памяти с старым кодом, но это вызвало-бы страшный бунт.
