Vladimir,

Tried actual CVS and problem is the same. 
Default is SIG_DFL and this is not the same as SIG_IGN.
SIG_DFL zombies a process and wait's until parent calls waitpid / wait3
/ wait4. It just delivers no signal to the parent thread.
If you set SIG_IGN the kernel removes this thread immidiatly from the
process list. As orphaned threads get parent process ID 1 (init) when
they are orphaned, they are not caught by a waitpid in one of init's
forks. Should be the same with daemons.
