Massive URL List For Expiration From Redirect Module

On a site that has been running for a long time we have 502 redirects and when we have the option in the Expire Module set to expire the menu family or the entire menu it usually returns about 78 menu item paths. When these paths are passed to the expire_cache_derivative function we get back a huge list of URLs each time the function is called which end up totaling over 10,000 URLS many of which are the same. This happens after the step where the Expire Module accesses the redirect module functions.

Not having enough working knowledge of the Expire Module or the Redirect Module I am thinking this is related to the redirect module which allows you to create redirect loops.

To create a redirect loop:

1. Create a node a URL is assigned to that node base on the node title.
2. Next change the title of that node to something new.
3. Edit the node again changing title back to the original title which should also assign it back to the original URL.
4. Now you have a node with a Redirect loop, fun.

Stupid as the situation is since the Redirect Module should just delete the conflict it does not even though it provide a message stating that the loop is present. At this time this seems to the source of huge URL expire list which is generated.
