We often call `parallel_for` in places with very variable sized workloads. When many elements are processed, using multi-threading is great, but when processing few elements (possibly many times) using `parallel_for` can result in significant overhead. I measured that this improves performance by >20% in the refactored realize instances code I'm working on separately. The change might also help with debugging sometimes, because the stack trace is smaller and contains fewer irrevelant symbols.
