Comment (by Lars Hagström <lars@…>):

 I just realized what the problem is!

 It's not a QPC problem after all. It's the static in steady_clock::now.
 I've got 50 threads trying to initialize that static variable at the same
 time, of course things go wrong :-)

 No idea of how to fix it in an efficient manner, though.
