Please show the results you see in the 2 problematic cases, and please
explain what did you expect instead and why.

FWIW, I don't necessarily see anything surprising in the results: you
basically let several threads step on each other's toes by modifying
the same variable with non-deterministic relative timings.  But maybe
I'm missing something, which is why I ask for details.

Or maybe Stefan could show me the light.
