Description
In configurations with many buckets (and especially with many shards per bucket), multisite sync generates http requests to /admin/log at an alarming rate. This produces an excessive load on the remote gateways (and could potentially tie up enough frontend threads to starve out other clients). There should be a way to limit the number of outstanding requests to a given zone.
