You are confused. You are Dazed.--More-- You have received enlightment. Welcome to level 34583. > This basically trickles up from libkvm, which presumably also wants to be > const-poisoned. Yes. Const poisoning is a post-order call graph traversal excersize. However, given the size of our call graphs, and their complexity, there are practical issues. In const-poisoning large systems, often times one needs to use half-measures, and bogosities like __DECONST to make progress.
