I'll certainly try it if I see it again.
After logging many hours over the weekend trying to get it to happen (with ProcessMonitor logging), I was utterly unsuccessful. After the three times, in quick succession, I saw it on Friday... nothing. Nada. It's maddening. I've come to the conclusion that having ProcessMonitor running is somehow actually
preventing the race condition from ever happening. I have no other explanation. I can probably easily confirm that by hitting it hard again without ProcessMonitor running. But I'm afraid that if it happened as soon as I turned off the filesystem i/o logger, I might gouge my own eyes out! That would mean the only way I can replicate it would be to ensure that I can't debug it. ARGH!!! I'm not sure I want to find that out!
