Sun long ago had a project to hot-patch the running kernel in limited
situations (mostly for diagnosis, or one-offs for customers for whom
rebooting cost more than the large sums of money required to custom
generate such a hot-patch), but it died not long later. Unfortunately,
it got some press coverage first that confused people into thinking it
was going to become part of Solaris, which it never did.
