It occurred to me -- in the page-search code, we copy the page's write generation, then search the page.

It occurs to me we should probably have a memory barrier instruction after we copy the write generation, otherwise the compiler might re-order that read after we've actually searched the page? (Or make page->write_gen volatile?)
