FYI, we're refactoring this in 0.9. If I remember correctly it goes something like.
No more "destroy", "destorySoon" and "close". Only "destroy". I can't remember if we decided that: - "error" will always call "destroy" or - a stream is guaranteed to eventually emit either "error" or "destroy" maybe isaac remembers. it's hard to reason about close right now because it means a few different things on different streams and overlaps with all the destroy stuff.
