On my 10.4 system, it seems to be a race condition: sometimes I see all three of these failures, sometimes just one, sometimes none. Again, only on 10.4 (Tiger), not 10.5 or 10.6. But the 10.4 machine I'm using is by far the slowest of the three so it is possible that could be a factor. Perhaps there is a race condition with cleaning up the p2c pipe from a previous run?
