:-(. Though this would possibly point to some missing barrier in the threads
code if less scheduling fixes it. Well, try with -O2 -g, a bit harder to
debug though (you can play with -fno-schedule-insns and -fno-schedule-insns-2
too). BTW, leaving out -DNDEBUG=1 already switchea on the assertions, whereas
-DDEBUG=1 enables extra debugging stuff (maybe the extra debugging stuff lets
the bug go away?).
