As discussed on IRC, this leaves us with a race condition between
close() and queued messages. The spec says that once close() is
invoked, incoming data should be dropped, but queued tasks to dispatch
message event will still be coming.
This race condition can of course be fixed without much difficulty. It
may be more difficult to similarly rearrange XHR specs.
I find it unfortunate that where the spec says "queue a task", most
(or all) implementations will perform those actions immediately. This
source of confusion for developers.
