I'm wondering if fsck uses any sort of tricks to do read-ahead
to prefect data for pass1 and pass2.
If not does anyone thing it might speed things up?
We could use a reasonably simple child process (or team of them) to
read into anonymous mmap areas shared between the master and child
to do this.
Any ideas, any hints on where the code would fit best?
