// Pass audio data between two RtThreads bi-directionally.

// The master thread starts a transmission;
// the slave thread should be woken up when there is data available,
// process the data, and send data back to the master thread

// Uni-directional RT-safe-queue.
// A light wrapper around __wrap_mq_...
