Basically, mongrel_cluster lets you run a "pack of mongrels" (multiple mongrel instances) on, for instance, ports 8000 to 8002, all talking to the same database. Generally used behind an Apache or nginx (or some other web server) load balancing front-end, so your users hit one url that is routed to one of the mongrel instances for servicing.

Parts of RoR aren't thread-safe, so it is possible to have your RoR application die a flaming death if it gets too many requests too close together.
