It also does not explain why SIGQUIT won't work (it is not blocked, I made my app print out the whole signal mask and SIGQUIT is not blocked), but since we don't use it anyway, this might be an entirely different bug and should maybe be ignored for this issues. so the next easiest thing would be to use sigaction(2) to get the previous disposition of SIGQUIT for your daemon and check to see if its handler is set to SIG_IGN.
