This does do much better than v4, but I'm still hitting oom with
stress.sh -n 50.  I tried a bunch of variations but haven't been able to
get it quite right.  I think I need to hold off on this one and get the
2.6.39 pull request out.

I'll setup a .40 tree that has this in it and we can fix the ooms.  This
is a great base for the work, and I'd like to add more items to the
delay, especially the initial inode insertions.
