#59: the hello reports jobs holding a granted slot, and the new pool claims them; kernel_links records the job groups a kernel owns, so an attach that finds the kernel gone still ends them. Darwin now gets a leader token (start time via sysctl), so a reused pid is never signalled. kernel.md spells out why replayed kernel frames are harmless after a crash restart.
