Description
This was originally implemented in #37, but the implementation turned out to be very buggy so I removed it in #61. Still, I think it's an important optimization even for a reference executor, as it nearly doubles our performance in micro-benchmarks.

Research direction
Start with src/lib.rs around line 257, then review the original implementation in #37 and its removal in #61 to understand the prior failure. Reproduce the relevant micro-benchmarks and determine the safe local-queue behavior; done means the optimization is restored without the bugs that prompted its removal and the performance improvement is demonstrated.
