It isn't needed at all. When a cached page is written, it's trying hard to
replace the page in the cache by a new copy,
to return the previously cached page. Instead, I copy the cached page and
return the copy, which is what it already
does in another instance. In the current version, not yet available (but
soon), I do away with the page hash
table entirely, so there's nowhere for the page hash chains to accumulate.
Page is smaller and simpler, with
a reference count but no lock.
