It might also be interesting to split Use/Revalidate cases into 2 sets: Where
the resource is in m_documentResources and when it isn't. Or even 3: in
m_documentResources, not in m_documentResource but live in MemoryCache, and not
in m_documentResources but dead in MemoryCache.

That's not necessary in this patch. I'm just trying to think of other useful
pieces of data for determining how we can make MemoryCache more efficient.
