send keepalives to peers on a network change #176

Closed billiegoose closed 5 months ago

I can't see any difference with or without this change. Still seems like an ungodly long time (5-8 seconds) between NETWORK CHANGE and ...stream-close.

Can anyone else confirm / deny ?

Testing using my test/manual/measure-reconnect.js script and switching networks. Note: I've even tried commenting out the conn.setKeepAlive(5000) line in test/manual/measure-reconnect.js to try and give this PR every advantage.

@mafintosh - this works... ish. But it would probably work even better if we pessimistically began reconnecting to peers right away, then aborted the reconnecting if it turned out the connections were still alive. Got any ideas how to do that?

Lets land this for now, making the call non optional

Eh, my LAN connections are still so slow I can't really measure an improvement. But I have a really hard time imagining this could have a detrimental unforeseen result so I feel safe to merge it.
