* most usages are drop-in replacements * occasionally the other convenience functions can be used * verify call-paths from core code to identify usages * ensure reseeding for all tests involving some kind of randomness... __Note__: some tests were not yet converted, since their usage of randomness is actually not thread-safe. This problem existed previously, since also `rand()` is not thread safe, albeit in most cases it is possible to ignore this problem, as ''garbled internal state'' is also somehow „random“
