v takuv slu4aj nqna da e zombie (nqma da e markiran kato <defunct>).
V krajna smetka ste byde osinoven ot init i ste si byde process kakto vsi4ki 
ostanali i ste zaema sistemen resurs.

Pak povtarqm zombie e process kojto e terminiral i ima  _parent_ (dori i init 
da e, vypreki 4e init ne se kill-va i t.n., za tova se proba s hangup )  , 
oba4e negoviq parent vse oste ne e pro4el syotvetnoto entry v sysent[ ] , 
t.e. zombito e kazalo exit() , i tova e "registrirano" v sysent[ ] tablicata 
na procesite i parent zakusnqva da go "pro4ete" i "mahne" ot tam po nqkakva 
pri4ina. 

kernela ne biva  da se namesva , osven v edin 4asten slu4aj : ako
parent v tozi moment umre , i togava kernel ste registrira tozi child zombie  
na init, za tuj se prasta i hangup to init ). Ne 

Ina4e normalnoto e _istinskiq_parent_ i da priklu4i slu4aq
