A zombie cannot be adopted, he is dead :) its parent has 3 ways to purge it 
from the system:
- manually, by catching the SIGCHLD signal (a.k.a. SIGCLD)
- automatically, by setting the SIGCHLD handler to ignore it (SIG_IGN)
- automatically, by dying. If the parent dies, the parent of the parent has to 
choose one of the 3 ways and if no parent exist, "init" does the job.

both DCTC and dc_gui2 uses the second way using the function set_sig() in 
main.c then there is no problem there. The problem is elsewhere but not 
within DCTC/dc_gui2 (I will have seen the zombies after 1 month uptime).
