> Robert asked for it. Calling random() (and its methods) can obscure memory 
> visibility issues (because random() is thread local, context-sensitive, 
> etc.). An option (or randomly selected mode) of running with a simple Random 
> (static/ test method level only) would simulate the framework as it was 
> before (reading -- possibly non-reproducible thread races but at the same 
> time testing memory visibility issues in the core code).
