When recovery on the receiving side started, there's almost nothing to
do for the sending side, it just has to wait until the partial copy
is ready to get data appended. In this time rsync on the sending side eats
95% of CPU time. I would say, that this is not the right behaviour, the
rsync process on the sending side should idle in this time.
