Have you tried checking the return code from exec?

Because on my system exec never returns, so quite how you are reaching the while loop I do not understand.

Try running this: 

perl -e"warn $$; exec 'notepad'; warn 'here'"

You'll see the pid printed & notepad start, but never see 'here'.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
