Communications Buffer

Each digital organism has a buffer of MaxIOBufSiz (default to 4) IOS data structures:

{   I32s t;    /* tag for type of message 0 reserved for free struct */
    ComAddr s; /* source address */
    ComAddr e; /* destination address */
    ComData d; /* data */
} IOS;

Messages directed specifically at an organism, such as TPing responses, are buffered there. Messages are processed in a first-in, first-out, order, and when the buffer is full, it beings writing over the oldest messages.
