I am confused how the $foo variable is locked in the functions.
Through the magic of perl threads? I'm sorry, I don't understand your question, but I don't think I could explain lock better than perlthrtut.

Maybe it would be easier for you to understand if you told us where you got that code, what its supposed to do, etc?
