> Dispatch is currently hard-wired to issue initial credit for 1000 messages and to replenish
credit by one for every received message.
> Recent research done by Mick Goulish suggests that better performance can be achieved
by batching credit replenishment by 10-50 credits at a time, thus amortizing the cost of flow
processing.
> Initial credit and batch size should be configurable in the router.  It might make sense
to have a global configuration and per-connection configuration.
