Best way to call async method from processBlock() loop?

I was referring to MacOS/iOS, where the message is posted into this array
in the MessageQueue class:

 void post (MessageManager::MessageBase* const message)
    {
        messages.add (message);
        wakeUp();
    }

messages uses a CriticalSection and may be dynamically reallocated.

ReferenceCountedArray<MessageManager::MessageBase, CriticalSection> messages;

Maybe this could be replaced by a lock-free Fifo
Wonder what @jules opinion is?
