There's no quota support in local storage (yet..I'll probably be looking at
this eventually). I don't believe there's any intention to have expiration
dates for database, LocalStorage, or AppCache, but there has been talk of a
LRU policy of eviction when devices are running out of storage space.

There's no standard across the APIs for doing anything like this. It
shouldn't be too hard to add to localStorage since it already has an event
system. Not sure about the others, but I assume it'd take more work.
