1) FF still seems to require explicit locking Actually, it's main claim to fame is being lock free (on Intel architectures). At most it requires a fence on weaker architectures (e.g. ARM) for one of the operations. You don't use a mutex to communicate between workers, you send a message over a (lock free) queue. Anyway, the auto-scheduling stuff in RaftLib looks pretty cool. Thanks for the response.
