Commit ID ccad6013892a95574e7c3ec652f3e03c357d10b7
Author Marco Costalba

Avoid locking/unlocking in a tight loop After previous patch if split point master is waiting for job and "Use Sleeping Threads" is false (our condition for official releases) then it will lock/unlock splitPoint mutex in a super tight loop badly affecting performance. Rewrite the code to lock only when we are about to finish. Note that race condition on slavesMask is anyhow fixed. No functional change.
