If I remember correctly, these work stealing task schedulers started getting pushed around the mid 2000s as a result of Intel failing to scale the Pentium 4 architecture to expected single-thread performance levels. Libraries like .NET's Task Parallel Library or Intel Threaded Building Blocks pretty much cemented these work-stealing task architectures. It's not that they didn't work well enough, but Intel Core came along, and single-threaded perf scaling was possible again, so these libraries became less of a focus. It seems multi-core interest is back.
