It prevents overload _while_ daemon loads updates to kernel.
2 seconds is just minimal value which is absolutely safe, because
route updates are delayed in any case.
"ip ro flush cache" is used to complete some kinds of updates,
which are not flushed automatically. F.e. in batched scripts
changing policy rule, when you want to be sure that cache
will be flushed but do not know forward, when batch will be completed.
What's about immediate flush, you can request it with:
echo 0 > /proc/sys/net/ipv4/route/flush
ip ro flush cache is equivalent to:
cat /proc/sys/net/ipv4/route/min_delay > /proc/sys/net/ipv4/route/flush
