At this point, turning "initialized" into a file-scope static, and 
building reinit as

        void promisor_remote_reinit(void)
        {
                initialized = 0;
                ... clear existing "promisor" entries ...
                promisor_remote_init();
        }

may make more sense.

The promisors and promisors_tail would need to be reinitiazlied and
existing elements on the list purged.  Otherwise, after removing an
entry from the configuration file, the entry will still stay around.
