Things that are about 1M big

So just throwing this out there for those for whom this might ring a bell. I’m debugging some CMS memory fragmentation issues on 2.0.5 - and interestingly enough most of the objects giving us promotion failures are of size 131074 (dwords) - GC logging obviously doesn’t say what those are, but I’
