It looks like this one is a heisenbug. I couldn't reproduce this and
Transarc isn't able to do anything with it either.

I tried this, my example is below. Note that this was on a Solaris 2.1 machine.

I did not see any problems here. I did the command three times only milliseconds
apart and the size of the file never changed.
