Is there another way to check what is going on with that anomalous lstat()?
I really don't think it's the lstat any more. Your directories look small 
and simple, and clearly the indexing made no difference.

See earlier email about using "strace -T" instead of "-tt". Also, I sent 
you a patch to try out just a minute ago, I think that may be it.
[ perhaps I will try 'perf' after I read how to use it ]
I really like 'perf' (it does what oprofile did for me, but without the 
headaches), but it doesn't help with IO profiling.

I've actually often wanted to have a 'strace' that shows page faults as 
special system calls, but it's sadly nontrivial ;(
