Small correction - I forgot to add setuid(0) ;)

PARENT CHILD
----------------------------------------------------------------
fork()
prctl(PR_SET_PDEATHSIG)
execve("/bin/setuid-binary")
setuid(0)
exit()'ed or killed
child receives NO signal this time

PARENT CHILD
----------------------------------------------------------------
fork()
prctl(PR_SET_PDEATHSIG)
execve("/bin/setuid-binary")
setuid(0)
execve("/bin/setuid-binary")
exit()'ed or killed
privileged process receives the signal
