which indicates the end of the variable-list, rather than returning nil,
which occurs when EOF is reached on input (i.e. the pipe from asterisk (AGI)
or socket (FastAGI) is closed).  So uncomment your line that tests for
        -- if line == "" then break end

You can implement almost any AGI script _without_ using non-blocking or
asynchronous I/O, which I've always found require some C functions rather
than lua's standard I/O library.
