+ * Contains a write message queue allowing
+ * for queueing messages with a notification callback. If the message receives
+ * an ACK, the callback is invoked.
+ * The special message TRK_WRITE_QUEUE_NOOP_CODE code can be used for synchronization.
+ * The respective  message will not be sent, the callback is just invoked.
+ * Note that calling open/close in quick succession can cause crashes
