Concurrent publishing issues?

[alanshaw]

I don't see any locks in or around NotifyPut - what happens if this is called concurrently? Can I lose an advertisement or is there some clever mitigation that I'm missing?

No clever mitigation - the library expects only 1 Put to be called at a time. If you're making multiple calls / publishing from multiple go-routines, you should use a channel to order / synchronize them.
Worth noting though that in this case you don't really want to be in a position where you're queuing up Notifys - or you'll pretty quickly see yourself getting rate limited.

you'll do much better to PublishLocal for something that's happening frequently, and then use a separate periodic announcement to get changes picked up.
