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.
