Is Boost using the right term there?


  In computer science, a non-blocking algorithm ensures that threads
  competing for a shared resource do not have their execution
  indefinitely postponed by mutual exclusion. A non-blocking algorithm
  is lock-free if there is guaranteed system-wide progress; wait-free if
  there is also guaranteed per-thread progress.

Lock-free does not mean that you don't have locks. It just means you
can't have deadlocks. You can't get stuck. Idealy what you want is a
wait-free algorithm.
