Let me know if there are some changes that should be done, I am testing this my self now and it at least has run two days in a row for me.
are you asking about MAX_QUERY_LEN?  I actually don't use that at all, but it seemed the other module had it in the generateQueries function.  I wasn't sure if it was expected that generators should accept this as input when calling... so I put it in but hadn't used it.   Actually I would like to take it out, but I wasn't sure what the "correct" way to call a module was going to be.
