Doing so makes sure that threads attempting to wake up new connections for a server will give up early if another thread is already in charge of this. The goal is to avoid unneeded contention on low server counts. Now with a single server with 16 threads in roundrobin we get the same performance as with multiple servers, i.e. ~575kreq/s instead of ~496k before. Leastconn is seeing a similar jump, from ~460 to ~560k (the difference being the calls to fwlc_srv_reposition). The overhead of process_srv_queue() is now around 2% instead of ~20% previously.
