There's definitely something fishy with this patch. I tried to see which of the two eager speculations were more profitable: cell or int32. So I created four total version of this patch: 1) Control. This has eager speculations disabled by having the actual functionality guarded by if (false), but everything else in place. 2) Int: only speculate eagerly on Int32 3) Cell: same but for cell 4) IntCell: both eager speculations. The results show a significant Kraken slow-down on Control. Will have to look at this more.
