This is what AcquireStoreRef/ReleaseStoreRef are for. We don't use
VMVnodeCache here because that is a non-"temporary" cache that
writes its pages back to disk, while we need a store for the pages
that won't discard unmodified ones when memory is low.
Add a close() to the mmap_cut_tests, which triggers the case where
this is important (a file is unlinked, mmap'ed, and then the lone
FD referring to it is closed, triggering the file's deletion unless
the mmap also acquired a reference to the vnode.)
Fixes KDLs with Firefox test builds.
