This had not been much of an issue as long as nobody was really interested in making any substantial changes to that code, but it is more apparent now. Torsten believes it can be partly because of a maintainer who is too busy with other tasks, and he suggested we try to improve the situation by giving the RNG-related tasks to someone else.

To play devil's advocate, does RNG subsystem need to evolve? Its task
is to get random numbers. Does it fail at the task?

Problem is, random subsystem is hard to verify, and big rewrite is
likely to cause security problems...
