Umm, there's a gem here that the thread missed so far:

           ^^^^^^^^^

There's no reason why it should do the lstat() *twice* for every file.
But Paweł is right; the code path roughly goes like this:

int cmd_cherry_pick(int argc, const char **argv, const char *prefix)
{
[...]
        res = sequencer_pick_revisions(&opts);

int sequencer_pick_revisions(struct replay_opts *opts)
{
[...]
        read_and_refresh_cache(opts);
[...]
        return pick_commits(todo_list, opts);
}

static int pick_commits(struct commit_list *todo_list, struct replay_opts *opts)
{
[...]
        read_and_refresh_cache(opts);


I'm too tired to dig further, but AFAICT it's just a rather obvious case
of duplication of effort.
