By the way, in this connection could somebody check my follow-up to the PR bin/48856? I suggested a really small fix (3 lines in total) to the current implementation of the signal(). With the current one the call of signal(SIGCHLD, SIG_IGN) still allows zombie to be born. There are to places to fix actually, one is the standard libc and second is the pthreads (that's why I am sending this message to -threads as well). If that fix is bad somehow I would gladly receive any explanations. Thanks! SY, Alex
