Thanks to Denis Shelomovskij for pointing out that due to
compiler optimizations the "Heisenbug" was still present in my
code, just very unlikely to trigger in practice. It should be
fixed for real now. I'll sleep over it and check it more
thoroughly again in the next days. Denis, I would appreciate it
if you might check if it looks good to you now.
