Tohle je velmi zajimavy stream: Bude slouzit jako nahrada standardniho in streamu - tenhle stream ma tu nevyhodu, ze je globalni, tj. je pro vsechna vlakna stejny. Ja potrebuji, aby tyhle streamy (jak out, tak err) byly pro ruzna vlakna ruzne, tj. aby kazde vlakno melo svuj standardni vystup - ale aby do nej mohlo normalne zapisovat pres System.out a System.err. Proto tenhle stream bude umet to, ze pokazde, kdyz nekdo zavola jeho cteci metodu, koukne se, z jakeho vlakna je volany a pokud je volany z vlakna zdedeneho od OwnIOThread (vi. tenhle balik), tj. prave od vlakna, ktere chce mit vlastni I/O, cte data ze streamu nadefinovanych timto vlaknem. Pokud vlakno nerozpozna (tj. neni zdedene od OwnIOThread), cte to ze streamu, ktere byl jako standardni nastaveny puvodne. (tj. jako by tam tenhle stream vubec nebyl).
