You could have a look at my lua4nt plugin (source code is in the public
domain): http://thomaslauer.com/download/lua4nt02.zip

I've not seen your code so I am not sure what I am doing differently but
my plugin definitely keeps state between invocations. The code is
neither overly long nor especially complicated, so it shouldn't be
difficult to locate the difference.
