There's more to it than that. Unfortunately, p9p's ls calls p9p's
readdir. Since readdir on Plan 9 has to return a complete Stat for each
file in a directory, p9p's readdir stats every file in the directory,
whether the caller needs the data or not (ls doesn't, without the ls
flag). That means that the p9p lc needs to walk to each directory entry,
whereas Plan 9's doesn't.
