Subject: [PATCH] routing/router: increase validation barrier size to 1000

This allows for a 1000 different persistent operations to proceed
concurrently. Now that we are batching operations at the db level, the
average number of outstanding requests will be higher since the commit
latency has increased. To compensate, we allow for more outstanding
requests to keep the router busy while batches are constructed.
