The level of task parallelism I have is north of 100M independent jobs; my last run took a single-core machine 20 days. It&amp;#x27;s pretty rare to have a workload like this but as more machines ship with &amp;gt;16 cores, I think more developers will look at the order-of-magnitude improvements of parallelizing their tasks where possible.</text></comment>
