I've tried running that specific test several multiple times and I
wasn't ableto see the failure. One potential difference from the
default configuration is that I use a configured LVM volume instead of
a flat file for the test files (i.e., I use /dev/heap/scratch instead
of a file named "vdc", for example). It could be that this is
sufficiently timing sensitive that I don't see the problem because the
race window is pretty narrow.
OK, thanks for sending the updated patch.
