This new design will work even when threads that need to receive messages from RT threads are created *after* the RT threads. The existing design would fail because the RT thread(s) would never be known the later created threads, and so signals emitted by the RT thread and causing call_slot() in the receiver would end up being enqueued using a lock-protected list. The new design ensures that communication always uses a lock-free FIFO instead
