Maybe a good opportunity to create a benchmark suite for tracking both, single- and multi-threaded performance over time?

It wouldn't introduce new static locking points. To the extent that it enables extra concurrency there's more opportunities for lock contention, but that's a good thing. :)

I 100% agree on the benchmarking idea -- we definitely want one of those.
