This is exactly what I think, and the reason I went ahead and
filed the bug with Apple even after you showed turning off Norton
making the bug go away. Norton may be able to cause this to
happen, but ultimately it's the operating system's fault.

Augie and Ben: Are you running Google Desktop, Spotlight, or any
other such program? We have found Google Desktop to be as much a
problem on Windows (where you can't even delete a file someone
like Google Desktop or your antivirus scanner has open).

Maybe try adding a bunch more load to the mix? Set off a few
make -j 4 builds, a few (sudo find / | sudo xargs cat) > /dev/null 2>&1
and see if you still get nothing.

Twice a year is not very often, so it may also be that you'll
have to let this run a while, and continue your other normal work
load, before finally triggering it. But the artificial load
might get you there more quickly.
