> This mainly fixes issues when we had "long" errors, for example a multi blocked when
trying to obtain a lock that was finally failing after 60s. Previously we were trying only
for 5 minutes. We now do all the tries. I've fixed stuff around this area to make it work.
> There is also more logs.
> I've changed the back off array. With the default pause of 100ms, even after 20 tries
we still retry every 10s.
> I've also changed the max per RS to something minimal. If the cluster is not in a very
good state it's less aggressive. It seems to be a better default.
> I've done two tests:
>  - on a small; homogeneous cluster, I had the same performances
>  - on a bigger, but heterogeneous cluster it was twice as fast.
