If this change were incorporated into the spec, our current implementations
would still conform, correct?  Allowing read transactions to start before a
read_write transaction is finished seems to give browsers the choice of
implementing an optimization without invalidating current behavior.

That said, we (chromium) wouldn't implement such an optimization for quite a
while, so when it goes into the spec is not of much practical importance.
