We don't need to do this in locore; we can do it in the same place where the old memory test was (which is before the VM system is turned on, etc.). I considered doing this when I removed the memory test code, but then changed my mind and decided that I wanted to know about problems with uninitialized memory. Perhaps when options DIAGNOSTIC is true, we fill memory with 0xdeadbeef and when not true, we fill with 0. ...or just fill with 0xdeadbeef all the time - I don't care. -DG
