I was so confused about why this mattered/made such a difference - until I went back and re-read from the top: OP does the benchmark timing in `main`, in the Zig app under test. If you don't do that, if you use the `time` CLI for example, this wouldn't have been a problem in the first place. Though sure you couldn't have compared to compiling fresh & running anyway, and at least on small inputs would've wanted to do the input prep first anyway. But I think if you put the benchmark code inside the DUT you're setting yourself up for all kinds of gotchas like this.
