Nobody would seriously propose a new thread for every branch. You would only consider eager threading for flakey branches, where you don't know which way they are going to go. And won't know for a while. Myself, I think non-threading approaches to eager execution are better. E.g. the discussion of short forward branches - emit colde that computes both sides of such a hammock, with operations like Phi nodes to bring back rto a single dataflow.
