someone said: "You should test the alpha in private... like other do too!"

If the alpha were not public then how would this bug have been discovered? There is a difference between INTENTIONALLY requerying at short intervals and a BUG. Luckily, the bug was caught before 3.0 went final, so it does not cause harm to the gnutella network at a large scale. XoloX and friends didn't care about the effects their aggressive re-querying behaviour would have (Don't even try to say that XoloX wouldn't/hasn't harm the the gnutella network. You just said that BearShare would harm the network with agressive requerying). XoloX dont even have public betas.
