I'm looking forward to taking a close look at it. I'm currently traveling until the 26th without a laptop and no email except for lore+lei+mutt on my phone. So I'll review this in about 1 week. But I'm very happy to see it here. On first glance, patch number 7 isn't okay. If you want this to work on 32bit, find an available bit for VM_DROPPABLE. Otherwise, just do this 64bit-only like many new features. Jason
