Well, since there is no documented guarantee, you should
not rely on it in any case, but I'm pretty sure it's not even
the case in the current implementation.

But what you get is the data that will be committed. So if
there are two consecutive writes, {t,K,V1} and {t,K,V2},
within the same transaction, you will only get an event
about the last update.
