That's good, I guess. But not good enough. Let's step back. Why is project-files so slow on your machine? In particular, why is it noticeably slower than project-find-regexp? Does the latest version of project-files in the branch, over 10 invocations, still take 11s? If so, you might have to investigate more, because I'm stumped. Does it build a meaningfully different command (aside from -exec) than xref-collect-matches? Does it return a different set of files than 'git ls-files'?
