Second one today (I blew off the first). You can blame someone else (releng is a particularly popular target), but you'll have to tell them wtf it means.

Looking at the log, it looks like PerfConfigurator at least believes it has/is generating the file.  Is it possible that we're so fast that run_test.py is trying to read the file while it is still in I/O buffering?  If not, its hard to guess without being able to poke around
