We're suffering from heavy fragmentation in some of our workloads. Add a build-time option to enable 4k pages (instead of 16k) in the GC, since that improves memory utilization considerably for us. Drawback is that this may increase the number of `madvise` system calls in the sweeping phase by a factor of 4, but concurrent page sweeping should help with some of that.

@kpamnany: could you approve it so that we have the basic functionality in place? Actually flipping the flag to enable it would be another PR, as usual. |
