Uh... oh.. never mind my terminology here (1st and 2nd level cache -
might be wrong), but as always Wikipedia is a good starting point for
understanding the problem of out-of-order execution and cache
incoherency (when using multiple CPUs - but I guess depending on the
architecture the cache problem could also occur on SINGLE CPU with
multiple cores, each having its own NON-coherent cache):
