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.
