That said, we have spent approximately zero time so far tuning this multithreading, and I'd be surprised if it scales perfectly the first time.

Somewhat related: Rust programs generally tend to have a better performance than their C pedants if they really want to. This is mainly due to the fact, that crazy thread optimization can be done securly.

A prominent example is [fd](https://github.com/sharkdp/fd), which uses multiple threads to traverse the file system, thereby being around 50% faster than find(1). Just the imagination of a parallel FS access in C gives me nightmares. :^)
