Isn't Full GCs a big problem? If have a bunch of pages in virtual memory, and need to do a full heap walk. Won't you basically have an exercise in page faults?
Realistically, doesn't that happen for any full GC though, regardless of how they're laid out? Even if the JVM requests a single large contiguous space, it will still be treated as many pages by the OS, and you'll get a similar amount of page faults. It doesn't matter what virtual address space they're mapped into. One of the suggestions I put forward elsewhere was having several zones (one per classloader); the advantage would then be you could GC each zone separately, and potentially at different intervals.
