* experimental: switch mutex to RW to see if it alleviates backpressure on peer info
* relax mutex req
* reject unknown messages
* open the floodgates
* adjust message handler to use goroutine, i'll probably regret this
* switch that back, it was regret
* further discovery
* log more data
* forcibly block channel when unbounded
* else
* make it configurable so bootstrap peers are the only ones putting up with this.
* ok, non-starter, let's try a different route
* further tweaking
* let the peer info flow uninhibited
* final burn off on master
* final adjustments
