Your suspicion about a race condition may very well be correct: I can easily confirm the problem on both iron and virtual smp, but not on a
single core virtual.
I have two instances of your test case running for half hour on the same core, without any problem: 30k cycles without hickup.
Apart from the immediate effect exposed by your script, I have reason to believe that the root cause also affects other running (smp) processes.
