[NMLUG] Random questions #26 (now tee...)
I too have written this program, and let me tell you if you don't clean up
after your children correctly your forking processes may die or become
zombies. So in my opinion, write your program on a test server, cause you
may be bringing it to it's knees.
or use tee.
