When some part of an application is hard or impossible to make fork-safe, but rarely called, it's possible to simply mark the worker as fork unsafe, and rely on its siblings to fork the next generation. In the eventually where all the workers end up marked fork unsafe, no new generation will be spawned, unless of course one of the unsafe workers die and is replaced by a fresh one. So this is only meant as a workaround for infrequently called things.
