wont you still suffer form disk access penalty still?
reading 1000 files = 10 second delay (assuming 10ms access time on disk)
and mmap eats as much memory as loading them into RAM (as soon as you
scan enough pages which is more than likely since linux typically block
reads 255 pages at a time into its read-ahead buffer)
