I should mention here that I suspect the Cleanest solution is to make DF_DEFER_INSN_RESCAN imply that we also shouldn't grab data from the blocks those new insns are in either. In this way one can create the block, link it up properly, and have everything Just Work later, when deferred insns are processed. But I didn't immediately see a good way to do that. r~
