-// makeEventsChan implements a channel of events with an unlimited capacity. It does so
-// by creating a goroutine that queues incoming events. Sending to this channel never blocks
-// and no events get lost.
-//
-// The unlimited capacity channel is very suitable for delivering events because the consumer
-// may be unavailable for some time (doing a heavy computation), but will get to the events
-// later.
-//
-// An unlimited capacity channel has its dangers in general, but is completely fine for
-// the purpose of delivering events. This is because the production of events is fairly
-// infrequent and should never out-run their consumption in the long term.
