A more idiomatic way of trying a non-blocking send on a buffered channel
and falling back to a blocking send inside a goroutine. This really needs to be fixed. The situation only arises when events are sent and aren't pulled off the channel using {Wait,Poll}ForEvent. Namely, if the event send blocks, the entire program will deadlock. Using a goroutine is not ideal because we lose a guarantee of order: that events are processed in the order of their arrival. However, it seems OK as a temporary band-aide for a situation that probably doesn't arise too often. What I need to do is implement a dynamic queue. Here is a reference implementation: http://play.golang.org/p/AiHBsxTFpj
