When a node is executed, it usually schedules other nodes. Right now, those newly scheduled nodes are added to a task pool so that another thread can start working on them immediatly. However, that leads to the situation where sometimes each node in a simple chain is executed by another thread. That leads to additional threading overhead and reduced cache efficiency (for caches that are not shared between cores). Now, when a node is executed and schedules other nodes, the first of those newly scheduled nodes will always be executed on the same thread once the current node is done. If it schedules more than one other node, those will be added to the task pool as before. The speedup achieved by this is hard to measure. I found it to be a couple percent faster in some extreme cases, not much to get excited about. It's nice though that the number of tasks added to the task pool is commonly reduced by a factor of 4 or 5.
