losslessEvents

The same events as events, with none ever dropped (#414).

Each collector has a queue of its own with no limit, so it gets every event that happens while it collects, in order, however slow it or any collector of events is. The price is that queue: a collector that stops taking events holds every one it has not taken. Collection subscribes before its first suspension, so a collector started undispatched misses nothing from that moment on. Like events, it replays nothing.
