Ok, that's good to hear. Now for some more testing: Al Viro just
pushed some fixes to the parallel lookup code that may fix this
problem. Al asked this question:

| Can that be triggered on 4e82901 + cherry-pick of e7d6ef979?
| Same for 9f541801 + e7d6ef979?

Those commits are all in the current Linus tree - would you be
able to test them? (i.e. check out tree to 4e82901, then just
cherry pick the single commit (e7d6ef979) on top of that).

Cheers,

Dave.
