------------------------------------------

Bela said:"We should NOT send back a join response if the flush fails. The joiner should block until the previous FLUSH completed"

> When joining with state transfer, the coordinator starts the flush, but
> the joining member stops it. This might lead to an issue because as soon
> as the coordinator casts the new view to everyone (and receives their
> acks) he starts processing the next request in the queue without waiting
> for the flush to be completed.
> I noticed this because I got a 'retrying flush' without ever seeing "...
> Running FLUSH...". So, flushInProgress is still true. The problem might
> arise in that when it retries it sets force=true and that could possibly
> cause a flush to start before the stop has been received.
> Not sure it is an issue, but just thought I'd bring it up.
