It's safer to guarantee that we always send a message for each state.
 Otherwise, code like this will work with network fetches but then suddenly
fail if pointed at a data URL:

client.onreadystatechange = function() { if(client.readyState ==
client.someState) doSomething(); };

It doesn't matter how many network tasks there are, though.  We can just
say that if the old state is (eg.) OPENED, and we're now in DONE, that we
iterate through all of the intermediary states, setting readyState and
firing onreadystatecomplete.
