That's not a very good answer, actually.  It almost sounds like "we
can't be bothered to implement it".  The real reason is that URLs are
not stored in the cache - hash strings are.  What's more, different URLs
may hash to the same object, so there would be no way to generate an
unambiguous list.

That being said, the FAQ is correct in that it would be a very expensive
operation - listing the contents of the cache on a large server could
very well stall it for seconds or, in the worst case, minutes.
