Currently glob.iglob calls os.listdir internally. Which means that if there are many files in the directory - a big list of them is created in memory. iglob should try to use readdir and be a "true" iterator, not consuming a lot of memory. See one possible implementation using ctypes at http://stackoverflow.com/questions/4403598/list-files-in-a-folder-as-a-stream-to-begin-process-immediately
