If they change really rarely couldln't you just have the children automatically die off when the stuff needs to change and reload it? You'd have to create the datastructure using a ChildInit handler i assume, but couldn't a setup like that potentially work?

I currently use a semaphore scheme to cache large lists within child processes that rarely change. It works quite well. If the semaphore is set, the child knows to re-cache; children set the semaphore when they do something that would require other children to re-cache. But, I'd like to do something similar; have a separate process that can alter parent data receive signals and re-cache accordingly. Maybe this is really bad idea? Would existing child processes see the new data or would the only have a copy of the stale data? Of course, the problem with using a database to get the lists (besides the lists being the result of a munge), is that they are rather large.
