If one such occurrence makes Emacs significantly slower for a common-enough use, it can be important enough to improve Emacs. And as I wrote, I'm sure there are more occurrences. > What's the difference, for the purpose of this discussion, between > having the code in C and having it in internal Lisp functions? The internal Lisp function would need an efficient way to get a file's timestamp. It can't do that if there's no C primitive to do it. > What we have established is that Emacs apps need to be able to measure > time intervals, not that they need a monotonic clock.

What other bases would these be? Monotonic clocks are relatively portable; other methods that come to mind are not.
