Description

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).
