Showstopper for 2.1rc1 resolved

[Oliver Zeigermann <ol...@gmail.com>]

For me this is no longer a show stopper as Mirko reported things are
fine with the tx file store and MySQL with caching turned on. We
should investigate this further, but at least there is a way to work
around this.

When thinking of a 2.1 we should not have a perfect system in mind
(which will never allow us to release anything), but something that is
better than 2.0 which is the latest final version. From what I have
heard even 2.1b1 was better than 2.0 ;)
