glad it's not just me.

I find the problem to be reproducible and so in theory it might be 
possible to generate a small reproducing test case.  
I meant to do that already but I got distracted 
by other things.

I think I managed to have a trace I recorded and replayed recreate the 
issue, but narrowing things down from a 2000+ syscall trace can be 
tedious.

Let me know if you have any other issues with the perf_fuzzer.
