/* The only actual reason for this queue is to enable non-blocking reads.
*  I.e. we want to avoid blocking the main loop while waiting on a user-input terminating '\n', '\r' or ',' .
* As we could (and DO if the queue is full) execute a command right away once all arguments have been read,
* the queue really does not need to be 4 long and the whole handling could me much much simpler.
* I.e. only ever remember ONE command and execute it as soon as all args are present!
