Subject: How to check if child process is still alive?

how do you check if your child process from fork still alive or not? In perl 
I can send kill(0, $cid), I think. But Process.kill(0, child_id) always 
returns 1.

To be honest, I couldn't get the perl code to work either. It always returns 
1 too.

I can do `ps -p #{child_id}` but I wonder if Process.kill should work too.
