I can (under debian) start gossip twice at the same time. is the locking missing here or can lmdb handle it? @Mike Dilger
I'm not sure. That hasn't been thought through. Try it at your own risk.
I think LMDB will be ok. But there might be race conditions related to downloaded images and such. And there would be far too many network connections to relays. So I don't think we need to create a global lock to prevent it from happening, but it's not advised to run two of them side by side.
