It's not clear to me exactly what you mean. This may or may not work
depending on how void handler() is written. I'll be interested in
seeing the patch, if you ever do it.

Anyhow, I'm not using libevent, I'm just reading the book to broaden
my exposure to lua idioms, and noticed that the code as written had
this subtle bug.
