I think a more reliable leak is to then write in the page, and see if
the write takes a long time (due to copy-on-write). There were other
potential information leaks discussed, but IMO they were all pretty
far-fetched and can be defended against (e.g., don't make it
predictable when pages will be merged; on the application side, when
inputting passwords, initialize the buffer with random data).
