I'm planning to keep that to me self, due to i think the other pools based on pushpoold will eventually face the same problem.
This issue costed the pool/me personally 10 BTC + a whole day of hard work with debugging, tcpdump and ~10 people that tried in all ways to help us.

If I'm about to release this, the pool need something in return.
We'll see if this is just an isolated issue with our pool, or if anyone else will face the same problem.
