You still need the 10s commit reservation. The reason being, replication
happens like this:
- Replica gets list of files from leader
- For each file, replica fetches the file from leader
After the first step happens, you need to keep the commit alive for the entire
duration of the second step which involves many, many requests. So you need to
keep extending the commit reservation between requests. I think the
save/release is clean for the duration of the write, you probably still need
the older release at the end of it..

> The ReplicationHandler should have an option to throttle the speed of
> replication.
> It is useful for people who want bring up nodes in their SolrCloud cluster or
> when have a backup-restore API and not eat up all their network bandwidth
> while replicating.
> I am writing a test case and will attach a patch shortly.
