Maybe don't. Maybe have a command-line switch to disable panic_action 
signal installers and document that this is needed for debugging?

I'm wary about the code. How does it interact with SELinux/grsecurity 
for example? Failure to be able to ptrace a parent process might be 
expected in some - many? most? - cases.
