You would still have to read the entire directory, right? In that kind of class, there is a number of applications; e.g. du(1) also wouldn't have to create a list of all files in the directory, but add the sizes of the files incrementally. So the question really is whether it is a problem to keep all file names in memory simultaneously. As Aahz says, the total memory consumption for a large directory is still comparatively low, for today's machines.
